I have here a unique old mechanical Stewart-Warner setup to drive two instruments. It came with a speedometer that I found some time ago. It's a 1:1 ratio Model 667-SN. It includes two cables, which are different sizes, the thick one possibly for a tachometer (69") & the thinner one for a speedometer (58"). They have the pre 1960's style connections, where the cable ends screw into the inside of the instrument drive nipples, rather than the outside. Everything is in really nice used condition. All that being said, I cannot comment on the crank drive (other than the fact that everything appears loose & lubed), since I never got involved in hooking one up to a flattie crank hub. I've seen these drives along the line & it's always been a mystery as to have the actual connection is made. And, included is a strange cable connector, which is also a mystery to me...see the last three pictures. It appears to have a switch on the side of it...maybe a drive direction changer? If you're building a car & want something that you will probably never see on another ride, this is your chance. If you need more pics or need to speak with me about it, let me know. The price is plus shipping....let's say $20, given the weight of everything. PayPal (F&F) would be best, but a Postal Money Order would work, as well. The first P.M. committing to buy gets it.
