Projects Vintage Delco-Remy Distributor Identification???

I found an old Delco-Remy Distributor Model 625F 7H9 on the tag. Trying to figure out what it is for? Anyone know or have a website for old distributor numbers. Thanks.

 

That may be a @squirrel question or a @Bruce Lancaster question.

I can tell you this it does not fit a modern engine.

 

According to what I can find, it should be for a late 30's-early 40's International truck - 4 cylinder.

 

Thanks for the response.
