I don't know, no brass 'friction disk' is used nor listed in the parts manuals -see LINK below. It is from 1946 but shows both the early 1939 PTO assembly and the later one. Tell us what you have and which part you are referring to. The original PTO splined end was 1-1/8" and later the AG engineers made it 1-3/8" which is the industry standard still today. The parts sold today will fit either shaft. Also go to our MANUALS forum and look under PARTS, open a MPC and look at the exploded views and part descriptions. The bearing housings, shafts, and most other related parts are probably made by a few suppliers. You don't need to buy off ebay -usually don't know what you might get. JUST8Ns, Dennis Carpenter, or STEINER are a few of the handful or reliable parts suppliers. there are 2 snap rings, a bearing, seal, bushing, and a paper gasket in the PTO rear bearing housing. Pictures would also be helpful. Look at Page 22 in the January, 1946 MPC - see LINK...
