No4 Bolt Advice

[Singer B]

Lucky you with the No.5 I mean.

Thanks. I hope it is in good shape. I've only seen pictures. It appears to be a BSA. I can see a couple of rust issues that will need attention and the bolt is mismatched to the receiver. I tried for a couple others over the last year but one turned out to be a fake and the other was too rich for my blood. Looking forward to picking it up, breaking it down, and starting the refurbishment process.
