For all you Vickers fans -
Last year I managed to get my hands on a Czech Vickers lock body in unused condition. The only one I've ever seen is in Dolf book and I knew exactly what it was when I bought it. It is different from a conventional Vickers lock as it uses 2 coil springs rather than the single flat spring to operate the trigger and main springs.
I modelled the parts and had them 3D printed. All but one part fit perfectly and - after modifying the cocking arm - I had it together and functioning in less than 1/2 hr. I used a standard extractor and left the trigger unmodified as I don't see a need for the spring loaded top at this point. The parts are a steel and bronze composition and I do not believe they would hold up well if used in a FA gun - however - I could have them printed from stainless which would. This lock is mostly for reference at this point although I now have the lock body modelled in 3D - it would be possible to have that printed as well. I'm not entirely sold on the 3D accuracy of the holes and required machined surfaces - the small items and surface finish left a little to be desired but this worked out well after I cleaned it all up. If I end up having a lock body made I will locate the holes but final drill them for accuracy.
Wish I was closer to Dolf - I know he'd enjoy seeing it!
