Hi,
BSF, or BSW, presume BSF given the finesse of those seen in my hand in the past, brass domed head slot head brass bolts,
all I want is a drawing showing 0ba 2ba etc etc, showing dims of dome diameters, size (width depth) of slots etc etc.
to draw them up.
Internet acts as if BSF never existed.
I like my charts as such , A B C D with little arrows, etc etc.,
can’t see any anywhere.
Cheers
Steve
