TRUMPET CORNET OLDS RECORDING MENDEZ OPERA THROW GASKET BUMPERS CORRECT SIZE

Description

TRUMPET METAL PARTS NOT FOR SALE, ONLY BLACK GASKET BUMPERS
Each order is for 2 (TWO) of these gaskets. These are hard to find, after much research and trial and error I have found a correct size and configuration replacement for the 3RD SLIDE throw "bumper/gasket".
I also have a supply of the correct ( a little smaller profile) size for the 1ST SLIDE throw for the Mendez/Opera/Studio model please indicate which you want, or if you want 1 set of each, 2 of each, etc.
Up till now I, like many with these horns, have had to settle for the round "O-Rings" available. I did have a few of the originals (see 3rd picture) to use as a pattern and did find some good quality Duro Buna replacements. These should last for years. Notice they are four sided, or square instead of the round O-Rings, see photo of original ( #3) and also how nice they "seat" or fit on the horn.I'm offering these at a good price.
EACH ORDER IS FOR 2 OF THE GASKETS FOR THE 3RD SLIDE THROW OF THE MENDEZ, RECORDING MODEL (See photo 4). These DO NOT work, nor are they designed to fit, the 1st year MENDEZ or RECORDING trumpets as those models have no ferrel to hold them in place.
Please indicate if you want these, for 3rd slide, or the 1st slide, or what combination of both in your purchase.
I have many Vintage Olds parts and pieces, if you need anything check with me.
