Delco Ignition Switch fits what?

We just had a key made for this Delco Ignition/Light switch. It has patent dates in 1916, "and other patents pending". The marque tag is missing from the front. Any ideas what cars this fits?

Thanks for your help!

Pat:confused:

Just off center on the back I think I can see a stamped number starting 12??

What is that number?

Layden:

You have amazing eyesight! the number is 1275

Pat

I have no listing for that number, 1275, would you mind rechecking? Thanks

Hi again Layden:

Definitely is 1275. I will take a pic and post a little later. Any other things I should look for?

Thanks, Pat

1275 is not in my Delco book but that is not surprising. Years ago I had a Delco double distributor unit unlike any I had seen. It was not listed and it wasn't until years later that I saw another on a Hispano-Suiza. Perhaps your combination ( lighting and ignition) switch is for a European application and could be Hisso if they purchased more than just the ignition from Delco. The 1275 number is between other numbers used in 1926 (year). The style handles and lack of names ( just letters) may hint at foreign sales for Delco.

My late Father in law purchased a collection of magnetos in the mid 50's. It also included some ignition switches.......This actually appears to be one of the more modern ones! Could have been European. "I" and "L" for ignition and lights would indicate english speaking? Great Britain?

I am surprised that it falls in numbering for 1926. I would have thought there would have been a few more patent dates over the 10 years from 1916

Thanks for your help, and thanks for checking. This is just one more in a long line of "oddities" we keep uncovering!
