hi, fish here. thanks for the interest.
i'm down to 45 ludwig 70's mach lug BODIES. they do not have the swivel nuts or springs. i believe they came off of marching snares as they are just under 8".
they are the same as what was used on kicks and floors back then, but perhaps 11" is standard on kicks and floors now. i don't have my ludwig dealer book handy to look it up right now.
the whole lot is priced low to go, so if you or he wants to see some pics hit me back and i'll send them. i'm in so-cal. thanks, fish
