I've been looking for a Starrett No. 104 speed indicator for over a year. All of them I found were either in fairly poor condition and missing attachments or were priced stupid high. Earlier this week over at Garage Journal one of the guys mentioned he had one that he'd had for years and never used. I got it in the mail yesterday and she's a real beauty. It came in it's original box, two tips in excellent condition, and even still has the instructions. It looks to have hardly been used. Plus, he priced it so low I felt guilty about it and added a few dollars onto the payment.
