One Inch Maxim Gun

Pack mules, these are some metal figures.  

The pack is an Atlantic WWII Russian Maxim Gun.

The US used a 1 inch caliber Maxim around the turn of the last century.

The Atlantic Russian Maxim is way too large for 1/72nd scale as a .30 caliber weapon.

So I use it as the 1 inch, it's essentially a larger version.

Here with Airfix MP for size.
