CamperDave Posted August 3 Share Posted August 3 Hello! I am helping with an estate, my friend wanted to toss this buy my curiosity got the best of me and I can't find it anywhere on the Internet and I thought I'd turn to you guys for your help. What I know is that it's possibly a braking mechanism sample made by Welch Scientific Company, with an outside braking mechanism on one side and an internal braking mechanism on the other side, both functional by pulling a brake lever. There is a label on the back that says "Lab model of automobile end 1920s". Any help identifying the device and providing value would be greatly appreciated. *This item is for sale and I also have a complete book set of Automotive Quarterly available if anyone is interested. 4 Link to comment Share on other sites More sharing options...
alsancle Posted August 3 Share Posted August 3 Neat piece. Used for classroom demonstration. Hard to say the value. I would put it on ebay and see what the market brings. Might be 50 bucks, might be 200. 3 1 Link to comment Share on other sites More sharing options...
KURTRUK Posted August 4 Share Posted August 4 Neat item. Just curious: what is the composition of the red wheels? Link to comment Share on other sites More sharing options...
28 Chrysler Posted August 4 Share Posted August 4 I have seen one of these along with a open 3 speed transmission to demonstrate the whole drive-train. The brakes would show how the differential worked. 1 Link to comment Share on other sites More sharing options...
