Two words when you have a desirable bike in the keeper fleet with obscure part sizing: "Donor bike".
+1 Based on my unscientific poll, out of around 300 vintage neglected bikes with cup and spindle bb, less than 10% were worn out. Out of 25 vintage neglected bikes with cartridge bb, close to 90% were worn out. So if you are stocking swiss cartridge bbs to save your stock swiss parts, better buy several.
