I personally found the castings to be on the rough side, and the directions that were provided to assemble the guns were not as clear as they should be. However, I think I managed and I have the photos to prove it. The 20mm AA gun was too delicate for my thumbs and did not survive. Each gun came with three crew members. It would appear that there are a total of four crew poses available. These figures are much smaller than 20mm figures from Platoon 20.
I allocated the the three extra crew men to two of the larger caliber guns.
