Hi Andy

(Edit – Andy, just seen how old you post is, your probably fixed up by now!)

In AP 1095 there is a section on Bomb Release Gear including the arming units and a 4 pole selector switch box. Possibly my copy isn’t new enough to have the 16/32 way selector in or the 16 way panels as it’s dated June 1935 but I suspect later versions would cover what you wanted.

The circuit diagrams of the bomber should have all the wiring in anyway, the Stirling circuits have the wiring of the 16 way and the later 32 way distributor and bomb release panel.

Found this – not what you want but derived from AP 1095 apparently and some interesting stuff in it.
