I have some mostly unmarked sets of Dunlop Grommets and I need some help identifying them. I figure if there is anyone who can help they are probably on this forum! Dunlop 1. This is probably a 90, 16x19, Skip 7T, 9T, 7H, 9H says PT164 YT090 16x19 under bumper, Top bumper is 13 5/8 in. x 7/8 in. 26 Holes in top bumper. 2. This set is also a 16x19 but much wider, Looks to be Skip 8T, 7H, 9H but could be 7T, 9T and not 8T (I know Dunlops go either way). These Bumpers and Grommets all have 703 underneath. 24 Holes in top bumper. Prince 3. I have a large package (7) Prince Oversize Conventional Series Graphite Grommets. I want to know if these are for the POGs and which ones they may fit (1-stripe, 4-stripe, and bumperless). Grommets are definitely for a 16 x 19 skip 8T and 8H which is correct for POG 110/107. Top bumper is 15 3/4 in long and side grommets are 10in long (may come up a little short on racket because it looks like part of it slides under the top grommet). Also in the Conventional Series Oversize: Pro, Spectrum Comp, Pro II, and Boron were all options but these are checked to be Graphite (6590) so this would be the correct era. Wilson 4. I believe Probably 110 or bigger, 16x20, Skip T7, T9, B7, B9 Top bumper is 15 3/8 in. x 7/8 in. Underneath just has numbers space is where grommet comes out: 22C- 2702 6230 BA (The Second row differs depending on piece: 2702(top), 2703(side), 2704(bottom). Unfortunately, not as helpful as numbers on Dunlops. Any help or information would be greatly appreciated so I can better identify them for potential customers. Thanks TW!
