I was looking through the Digital Files available from Wargames Atlantic, and came across their Great War Russian 1910 Maxim Gun and Crew. I'm not sure how long it has been available. I rarely look through the digital files,as I don't have a digital printer.
The Maxim Gun available in the Digital Files showed its water jacket fitted with a snow cap. The snow cap wasn't fitted on the Maxim gun until 1939. Hopefully it's not too late to upgrade the files.
I really enjoy you plastic figures,and have quite a few sets of them. I wish that Only-games offered more digital prints than what is listed on their site for sale.
