Ilya, the vintage "mach" kits are relatively rare. I don't think you will be disappointed with it. There were two Ludwig mach kits, the first "Mach 4" a four piece in 1974 and "Mach 5" a five piece, I believe in '75.
Check these out. The guy in the photo was selling his kit last week. These are Monroe badge (2001) date stamped, black sparkle kit. This is one of Ludwig's offerings using the Mach lugs and was a special order back in 2001. On Ludwigs web site you can custom order kits with mach lugs.
Note the top two 6" and 8" are 70's B&O toms. He wanted $1200 for the whole set-up seen here including a gorgeous set of Sabian AA's with an Ed Shaughnessy 21" ride and all cases. A very decent deal, but I have too many kits now Eye Ball
Mach lugs were also used originally for years on Ludwig marching snares because they allowed for higher tensioning of the heads required by Drum Corps. The first drum I ever played was a 1971 Ludwig 15" stainless marching snare with Mach lugs. There is something very delightful about the long mach lug. I converted a silver wrap marching snare into a floor tom for one of my kits because of them. Awesome!
