Rare Old wood & metal Rat ~ Mouse Trap

All though I have seen several of these I do not know the name of this cool rat trap as the paper label has worn away with the years but it is a factory made trap. This trap has very strong spring and it has bent the small brad that keeps the rear wood panel in place. [See last photo] This why I have the match in place to take up the slack. I was going to put a bigger nail in the hole but will leave that restoration project up to the buyer.
