It has been a few days since posting, but I have been busy trying to work out how to make the connecting arms, from the firing platform to the trail, these need to lock rigid when the gun is on the firing platform, unlock and fold while still attached to the trails,when raising to the locked up position, it took sometime to work out using photos, but I got there, I used and modified the arms from the kit, then made the central arms that have cam operated pawls that lock front and rear arms together, and a locking tab at each end, still needs to be cleaned up and painted, this should be the last of any major work the rest is window dressing
