Just reassembled an old safe lock, finally

Spent two hours on a 1940s vault tumbler I found at a junkyard. The spring was rusted solid, the pins were fused like they’d been in a war. Took me three tries to get the alignment right—first time I over-tightened and cracked the housing. But when it clicked open? Like hearing a breath you forgot you were holding. The smell of old metal and oil… still gets me. Not much to show for it, but sometimes that’s the point.
