mmuehlba Posted November 6, 2013 Report Share Posted November 6, 2013 well it is not a shift knob but the end for a Boyce Moto Meter radiator cap . I think they were made in the 20's so any ideas as not a lot of companys out there at that time might als be newer bit made for cars in the 20's but it might be a after market ?/ Mike here is the one I have . it is about 1 7/16 in dia and the insert is 5/16 fine thread 5/16 -24 Link to comment Share on other sites More sharing options...
Steph Posted November 6, 2013 Report Share Posted November 6, 2013 The only company I specifically know of actually made them out of stone -- the California Onyx Co. .... aka the California Agate Co. I take that back. I'm pretty sure I do remember seeing listings for a company which made them out of glass -- or at least distributed them. I just wasn't paying that much attention because I was interested in the stone ones. I'll see if I can find that company's name. In the meantime, here is a 1925 ad featuring an onyx radiator cap. http://www.ebay.com/itm/290658930288 Link to comment Share on other sites More sharing options...
Steph Posted November 6, 2013 Report Share Posted November 6, 2013 Well, I may still keep looking but Globe sounds right for the name I saw the most back when I was looking for info about stone radiator caps. Note the "Crystal-Onyx" name ... which frustrated stone onxy sellers and led to a case before the FTC. A 1926 ad for a Globe Specialty Co. cap which has the winged wheel on it like the ones you showed above: http://www.ebay.com/itm/300503465116 Link to comment Share on other sites More sharing options...
Steph Posted November 6, 2013 Report Share Posted November 6, 2013 That 1926 ad mentions Ford but isn't quite clear about why. This ad makes the Ford connection more clear: http://www.ebay.com/itm/290513980459 What exactly do you mean by "after market". If a Ford dealer installed it after it arrived from the factory, is that "after market"? I do remember seeing ads in newspapers so people could get them at stores and not just from dealerships -- at least I'm pretty sure the ads were for department stores or hardware stores or something and not dealerships.

mmuehlba Posted November 6, 2013 Author Report Share Posted November 6, 2013 "If a Ford dealer installed it after it arrived from the factory, is that "after market"? yes that would be an after market , mine are glass and I think the ones in my pictures are also , had to be made where they mage glass shift knobs and they would also be after marker as they were not put on on the assembley line .

Steph Posted November 6, 2013 Report Share Posted November 6, 2013 Got it! Thanks. I agree the pictured ones are glass. I think the ones in the 1925 ad I linked to could be natural onyx. The ones in the 1926 ads would be glass. Link to comment Share on other sites More sharing options...
TerryT35 Posted November 7, 2013 Report Share Posted November 7, 2013 Hey Mike, The logo on your Moto-Meter looks like the Indy 500 logo. Maybe it has a race connection?! Or a souvenir type item? Link to comment Share on other sites More sharing options...
mmuehlba Posted November 7, 2013 Author Report Share Posted November 7, 2013 Terry never looked as it is just a picture I have from the web . but I do have 3 of them the one single and a matched pair , I am listing the single one on the bay tonight thought I might get more info . Still thinking about making a display out of a shift lever from an old truck top shift trany , I have the stick and it is nice and long just waiting till I get some down time . my first gear shift knob cost me $2200 but it also came with a 5 window model A 1930 still have the know but no coupe . Boy made me think as I dragged it home 35 miles with a tow chain , only took a few hours to get it running . any ways just thinking back . Mike looking at the picture remember the door knobs ?? see mine ? Link to comment Share on other sites More sharing options...
