I discovered long ago that once a part was irretrievably lost forever - and I either went without it, made a new one or ordered a replacement part, it would mysteriously turn up weeks/months later when I was looking for something else.
Actually, I remember one instance when I "lost" a relatively large piece (a 20mm gun barrel from a 32nd Spitfire) AND...while sitting in my recliner one evening, my CAT brought it to me. But...unlike myself, she's never broken anything - despite her apparent agility (see attached)...and I NEVER tried to get her down from there. She got up there without any "trouble" - she'll get down the same way - and she always did.
Go figure. 🙁
