If they are a scotty cameron bulls eye then you can send it to the SC Custom Shop...

Just thinking....

Hi,  We offer a refurbishing for the head, but don't have new shafts or grips.  If you do want to set that up, please take your Bullseye to your local shop and they can set that up for you.

I have one of those classic Acushnet Bulls Eye putters as well.  Made by John Rutter Jr (Made in the USA) with the original leather grip on it.  Not really worth anything other than something to hang in the mancave. 

I've got two of them.  I had found a company that said they did rework on the Bullseye and sent them a query about cost, etc.  Never heard back from them.  Probably not worth the expense to do it, even though I used mine most of the time from when I bought it in '68 or '69 until the end of last year.

I break mine out when I know I will be playing very fast greens
