I restored this rusty $1 can opener to find out It’s worth MUCH more --- AF invention

I got this ancient looking can opener for just 1€ to restore it. While restoring it I found out it was not a worthless vintage item like I thought… The can opener is pretty rusty and the old paint is partially gone. Also the wooden part is pretty bad looking and there is a bit of mold on it. Sometimes looking for items to restore I make similar finds which I could flip fast for good profit. My typical projects are so laborious and require me to buy expensive parts so they are not usually good for making profit. So far I’ve kept all the items to myself. However it would be interesting to occasionally post videos doing restorations for business and flipping flea market finds for profit.
