Thanks for replying, guys. I measured the snares and from the metal plate at the throw-off end to the end tips of the snare gut wires is a whopping 17 1/2 inches. I cannot locate a number on the snare plate. If so-now what?
When I saw the image you posted I thought that maybe you have the incorrect synthetic gut "wires." The parts catalog shows the length as 16-1/8" (see the parts catalog image, part #9) and I'm assuming that is for the 14" drum. Without a parts number it would be tough to figure out if you've the unit for the 14" or 15" drum. I couldn't find measurements from the older catalogs for the either size, but they do have different numbers. Also, I don't visually know enough about the Super Sensitive parts to rule out that you have of those (see attached image).
I've attached some catalog images for your reference. Including the P-87 with a P-32 butt.... it was on the Ludwig No. 902 "Symphonic" snare.
...What I am now trying to find out is if this snare, when factory issued, had gut or wires. Do you guys know? From most pictures I can find, I can't see the bottom. Maybe 80s era non-marching snares had wires? ...
The drums were optioned so that you could have a choice between the different snares, however I would think that the wire option was the most common... and I have no data to back that up with though.
If you don't want to go to the extra expense of the L-1110, you can use the P-32 and a standard set of snare wires. I Don't know if I shared this earlier, but here's a link to my Coliseum snare mods: http://www.vintagedrumforum.com/showthread.php?t=30979
