Inherited Hobart Welder/Generator trying to learn Its history

I'm reaching out to see if anyone can lend me a hand. I recently inherited an old Hobart welder generator from my uncle's barn, and it's been sitting there for decades. It still turns by hand, and I'm eager to get it up and running again.

The data plate shows it's a GR-303 with a Chrysler IND-32 engine, and the serial numbers are still readable. However, I have no clue about the year it was made or what the original paint color might have been. I'm really hoping to restore it as close to the original look as possible.

If anyone has any info about the history of these old Hobarts, the factory color codes, or where I might find a manual or parts diagrams, I'd really appreciate it! This would be an awesome project to help preserve a bit of family history.

Cool find! The GR-303 with a Chrysler IND-32 likely dates from the late '40s to mid-'50s, based on Hobart's production and engine pairing during that era. Do you happen to have the engine's serial number too? It could help pin down the year more precisely and there's a chance Hobart manuals from that period are floating around in welding supply forums or archived military surplus catalogs.

bro, with the serial numbers visible, you might be able to get the exact year from Hobart directly. Many manufacturers keep old production records. Reach out to their customer service or archives department
