Hi to all,
I am writing again asking for help. During my research I found many late 18th century cannons (most of them 8-pdr, 12-pdr and 16-pdr, sevillian) with screw holes for the flintlock system near the basering and the upper proximal part of the first reinforce; on the back of the lamp, frequently are placed capital letters behind them (i.e. A, B F), which they seem to be used for the placement of the breech sights during the civil war period, as they have been reused and adapted. I wonder if someone could suggest me the best treatise/bibliography/paper on sights, where I can analyse their dimensions and, of course, get the space between the screwholes to let me know the exact model used. Also I would appreciate any information about manuals or instructions of the mounting of the sights that could clarify the capital letters placement, evidently part of that manual/printed instructions.
Thanks in advance,
