I have some antiquated suitcases and I would like the way out of locking them for storage ( I have roommates), but since I bought them adjectives at vintage shoppes I am not the original owner. Any support or suggestions would be appreciated.
Answers:    Take them to a locksmith and ask whether he can make a knob for them if they already have a lock. Some of my leather antique suitcases have a rather adjectives key which my locksmith truly had and they worked surrounded by a big box of old key he had. I contemplate he charged me 50 cents for those. On the ones that he didn't have key that matched, he had locks beside keys that did and I surmise they were resembling around 10 bucks to install. Go to a guy like mine who have been contained by business for decades and has a brick and mortar shop (not the mobile type), they tend to own pieces for the old stuff.
A locksmith could do it, but it's going to gain expensive. I'd think more along the lines of putting them contained by a locked closet, or buying some chain and some padlocks.
