A woman I know was going to sell me her father's razor. And after much convincing, I told her I would buy it (I didn't want to because it belongs to her and I wouldn't feel comfortable buying something her father left to her). Nonetheless, she said that I could pay her anything that I think is fair. I told her I would look into the going rate and let her know. I should have snapped a pic, but I didn't sorry.
It was gold and as far as I could tell, there was no date code (how obvious are the date codes? I was looking for like 10 seconds and couldn't find it.)... It looked like a SS but I'm not 100% sure as I haven't looked at many razors. I guess I'm looking for all gold Gillettes (most importantly before 1950) and their going rates.
