Looking to identify this font from an early 70s postage stamp

I've gone through as many font identifiers I can, including those that search by description of the letters. The serif on the A and J are particularly unique and difficult. I'm totally fine with a font that's "close enough" at this point. I'd prefer free fonts, but I know that may not always be possible.

Info: Postage stamp originates from Austria, dated 1972.

I've included a couple of the stamps for reference (the one on the left was my starting point). File titled "font sample" was my attempt with isolating the text for searching... which yielded me zero results.

Thank you to anyone who's able to help. I appreciate it!
