I have run across some more information on Russian WW1 tank designs, I hope Stoyan/or any body else can shed some light on this for us.
Zhitonoski Tankette (Shield Bearer) was a private venture designed as a one man vehicle with a prone driver/gunner. Maxim MG in limited traverse barbette in the nose. License built Italian engine as in KS (Russkiy-Renault Tank). Though ingenious this vehicle was too much for one man to handle it was not adopted but 16 were built for trials. Specs: 2.25 tons Crew: 1 7.62 mm MG Armor: 10mm Engine: Gasoline, 40 hP, 15 MPH (estimated)
I found a picture, and with the help of Eugene,he translated its title, to our surprise it was the Shield Bearer.
Looks like - I think the info you had came from Milsom's book (the sketch is the same), but as that was published in 1970, I'm not surprised at any inaccuracies. Dodgy name, I have to say...
