First time I have seen one of these
My guess it's one of the improvised mortars used at Gallipoli. The AWM has a Garland mortar
which was manufactured in Egypt - it was quite crude but apparently worked fairly well.
The projectile for the Garland and this mortar was probably a jam tin bomb.

Thanks, the elevator looks borrowed from a two inch mortar.

I agree - new one for me. The IWM has one but no image on line. The 4inch mortar seems to have been deployed in tiny
numbers and was withdrawn when the Stokes mortar became available. The text on the IWM website seems to tell most of the
story of the 4 inch http://www.iwm.org.uk/collections/item/object/30025462.
The 4inch tube - a bored out 6inch armour piercing shell would have been very expensive compared to the Stokes' length of seamless gas pipe.
New one on me, too, but it seems we have been unkind to Wikipedia on this occasion: https://en.wikipedia.org/wiki/2-inch_Medium_Mortar#4_inch_mortar
