SGS: hard to tell condition from that one picture, but that is a very popular design and guessing early to mid 80's. if it's not rusted and has the lock and key with all the drawers working like they should maybe $300 in my area, but i'm on the other side of the US from you. I sold the bottom box to that duo last year for $400 that was in similar condition.
post more pictures if you have any. also pricing is EMPTY and not full of tools which would be a bonus.
