Hi Dan and David,
I think our wires must have crossed somewhere!
The one that you are working on Dan, is the Barry Walby MMS PaK43 (short ammunition box), which was released after the Pak43 I did for Hinchcliffe (long ammunition box) in February 1986. The MMS one is more for modellers, whereas the Hincliffe one was more for wargamers hence slightly more bulkier as requested.
Out of interest, Skytrex became the trading arm for Hinchcliffe and when Skytrex was taken up by EWM, (Early War Miniatures) more recently. EWM still stock the PaK43 with better castings now.
Sorry to slightly hi-jack your thread Dan, it was not my intention. The Pak43 of yours Dan, is really looking good and really doing it justice. You may guess that the PaK43 is my favourite anti-tank gun, so futuristic for it's time.
All the best
