MAIN BEARING BSA B+M JAPN - Use 37-7041
A main bearing reference number that the catalog directs you to order as 37-7041 instead; later superseded by 57-1070.
This number, 65-2045, shows up in the records as a main bearing listed for BSA under a B+M Japan designation, but the catalog note tells you plainly to use 37-7041 instead. Whatever this part originally was, our books point you to that other number for the actual item you'd order today.

There's also a later factory number on file, 57-1070, which superseded this one down the line - so if you're chasing this part across different parts books or old invoices, you may see it listed under either 37-7041 or 57-1070 depending on which reference you're holding.
We don't have more detail on this one beyond what's in the catalog note itself. Call the shop and we'll confirm which number you actually need before you order.
