Hi All

I picked up a Howard 12s 17j serial #1233876 in a Crescent Extra case. The main spring is broken. Would anybody be able to tell me the proper main spring I should be looking for. A part number would help. I have seen three different 12s main springs listed on Ebay.

Regards,
Keith

Keith,
If your mainspring is a T end, I have one. If it's a hole end, the part number should be #552.

I have a 552 if you need that one. Contact me at; david@glopar.com
