I bought the new 1/72 Firefly, and it has a little 50cal machine gun (part B5) that I'd like to mount on it. It is marked as unused, and I have no idea how and which parts are needed from the unused ones to mount the gun nevertheless. (Historical accuracy is not a concern

If anyone has other DML Shermans which do have this gun mounted, please send me which parts are used for that.
thanks and merry Christmas!
