MK1 Tank Lewis gun question
Permalink   


Hi All,

While working on the sponson drawings for the 1/6 scale MK1, I came across a photo of the Lewis gun and noticed it seemed to have an extra part to it. From what I can tell it is an extra bar above the barrel to protect the sight and tip from rubbing on the flap.

I don't see it on lewis guns used away from tanks, so have I guessed its use correctly?

I have asked the same question some time ago, and in the absence of a definite answer, I came to the same conclusion. However, it is a Hotchkiss not a Lewis.

Well ... maybe the answer is much more simple. And it is not just "to protect the sight and tip from rubbing on the flap". Imagine you are the gunner. How do you aim your targets? By using the "backsight" (hopefully this is the correct word). But .... how could you use it when the flap rubbs on the barrel? You can't, because your sight at possible targets would be zero.

Just my point of view.

Ha, ha, ha! Oops... put my foot in it there. :D It's a Hotchkiss Portable MK1, I should know this as I have a photo of one being used inside a sponson of one of the Gaza tanks. Teach me to pay more attention. no

Just can't believe the lack of info. Going to keep looking.

My word. How very observant of Helen. Never noticed that before. Have scrutinized several bits of film of the Mk I and not been able to spot another example. Of course, elbavaro's theory is spot on and so obvious, assuming that there was no method of locking the flap so it remained clear of the barrel. The next question is one I've been meaning to ask for ages: was there a mount of some kind on the Mk I for the Hotchkiss to sit on, or did the gunner just stick his weapon through the aperture? (I chose my words quite carefully there.)

Somewhere, a long time ago, I think Ironsides found the manual for the tank version of the Hotchkiss (which went under a variety of names - M1909, Short Hotchkiss, Hotchkiss Portative, and Benet-Mercier)

Later . . .  Oops, no. It turns out it was me. http://www.scribd.com/doc/11491634/hotchkiss-manual-1918

Scroll down over 3/4 and there are 2 pics of Tank version "adapted for use outside tank". Still not clear to me if swivel was omnidirectional.

There's pictures of it in both British cavalry and tank configurations at world.guns.ru/machine/fr/hotchkiss-portative-e.html. There's also an illustration of it with the "Mk II cartrige case deflector, with bag and belt cradle assembled," (for use with the linked semi-rigid metallic belts), "As supplied to the Tank Corp" at fauerzaesp.org/foro/viewtopic.php (half way down the page - post Sep 07, 2009 by "legonaire"). That's a picture hosted on ImageShack - don't delay saving a personal copy if you want one, in my experience it's a miracle this one has lasted almost 4 years already and I have no idea of the original source.

Sadly, none with the flap-clearance bar/rod modification.

Perhaps it's some sort of rudimentary sighting apparatus? BTW I doubt this weapon is the often seen Lewis gun. Even stripped of its cooling jacket (which might be unusual for ground use, only "aircraft" gun were stripped to make them lighter, refrigeration achieved by airsteam) this gun seems to have a lower "spring" barrel much more robust than the usual Lewis gun (see diagram).

In any case, could this in the tank be a French Hotchkiss?

d fernetti, it's neither of those two weapons, the Hotchkiss .303 is the portable version as mentioned above, much smaller, and in 'normal' use had a bipod - the British cavalry used it instead of the Lewis too. It must be to raise the flap to be able to aim it as otherwise it would not be possible at all, and no other Hotchkiss's had it

Diego: this is it: http://www.landships.info/landships/weapon_articles.html?load=weapon_articles/Hotchkiss_Mle_1909.html

elbavaro: that makes a lot of sense.

Ooh. I'm not convinced by the tank version on the world.guns.ru site, are you? What did it attach to?

I think that is just a "display" mount on that website - the rest of the configuration is probably okay. I posted (and edited) before seeing your specific queries you see. What do you think of the picture of the page on that other (fauerzaesp) forum? The cartridge deflector I hadn't seen before but (trust me) would have been a fairly essential piece of kit. Well, not compared to having your head shot off perhaps but a .303 cartridge case down the shirt front, hot from any sort of automatic weapon, goes way beyond merely "uncomfortable" - and those things are ejected with real force besides.

There was a mount similar to the mount for the Lewis, except it was oval not circular. There is a photo of a Mk I with the flap missing, and the oval aperture in the mounting can be clearly seen.

Here are a few photos...

The first two are mine and show the bracket on the MK1 sponson at Bovi. The gun it seems hooks into the centre part, which allows vertical movement, and because it is pivoted top and bottom, horizontally.

The black n white scanned photo I purchased from Bovi, as such I may be wrong showing it here, but it it gives a clear view of a gunner in position with his harness on and the gun locked in place.

Lots of info everybody, Thank you x

Fascinating, Hel. Ta ever so. The gunner in pic 3 seems to be using the fore and back sights without any problem. I can't work out if there was any way of propping the flap open and clear of the barrel. And, for that matter, locking it shut to prevent the opposition firing in.

Very interesting. Any known purpose for the "mailbox" below the machine gun mounting? Note also on the B&W photo that there's some type of tool and leather pouch hanging from the upper slit fixture. Perhaps these things are related to the gun and are tools for fixing an ammo jam?

The leather pouch is indeed the tool kit pouch - the slot could be a housing for it

Hi,

The mailbox looking thingies are the vision ports. Below the gun in the colour photo and above in the black n white one. The bolts are on the centre line, with the vision slot below and the shield pushed above (Not worked out how). On later tanks the bolts are offset to line up with the shield part, maybe to give it more strength.

Thanks for the explanation! One wonders why they somehow decided to change the vision port location. Maybe gunners wanted to duck instead of looking standing up?
