Technical I bought a chain driven blower drive for a nailhead originally from California. Was it yours??

I know this is a long shot but here we go. I just purchased this blower drive for a nailhead. Chain driven. I came across an article in Bangshift.com from 2015 about the very item I purchased. They have it listed as a Howard Cragar blower drive. They talk about how it’s for sale on eBay and the guy selling it has other old hot rod stuff like a 32 3 window project etc. Fast forward 10 years and the link to the original sale listing doesn’t work. The guy I got it from isn’t the guy who bought it from that listing

The short version of this is I’d like to know the history of the drive and have a couple questions for the guy that sold it originally. I guess that dude is the one who actually removed it from an engine. Are you that guy? Have you seen this blower drive before? Do you have one? Thanks guys.

 

From awhile back.
