Assembling the gun cradle - oh, what a mess! There are four dimensions which are relevant.
1 - The spacing of the two notches on 103B
2 - The separation of the gun pivots
3 - The bar on 100B which has a peg that fits into a hole on 101B
4 - The length of part 104B.
No two of these dimensions tally at all. I considered the distance across the gun pivot points the critical dimension. If that was too great, not only would the gun droop, but the end of the gun would be able to move in a circle. To begin with, I had to deepen the notches on 103B to bring 100B and 101B a little closer together. The rod on 100B still only covers around 2/3 of the gap to 101B. There is no way to get that to fit as it is cast. Assembling 100B, 101B, 97B and 103B correctly is next to impossible due to the very poor design of the parts. I had to have three attempts before I ended up with something I could (barely) live with. I actually fitted the gunshield (106B) before assembling the gun cradle so that I would have the gun barrel mounted facing forward, rather than at an angle.
When fitting 104B, I found that the end of 100B was not only malformed, but the locating hole was in completely the wrong place. 104B was also around 4mm too long.
Both parts 107B are a bit too short too. What i've ended up with is a bit of a hack, I'm afraid. If I was doing this again, I would be resorting to a few lengths of brass tubing to act as the gun pivot, the too-short rod on 100B and 104B
