Hi Allan, as far as I know the firing data came in via cables, to two sockets mounted just above the elevation wheel, I have not modelled these yet, this lit three lights, and pointers were manually moved to cover them, this set the correct information, for firing.
Bonjour Yves, hows the 222 progressing, you have not posted any pictures.
I have continued on the cruciform this weekend, first I made two new sprung loaded bolts, for the out rigger securing arms, and the sprung loaded top brackets for the stakes, and the L shaped bottom brackets, the stakes can now be removed without unscrewing a bolt, I also made the four stake removal tool / spanners, these are made from steel, brass and alloy, new brackets need to be made to fit them, next job!
