That's a nice scraper plane you made Jim 👍
I'm maybe more of a hoarder than a collector! I don't look for anything in particular but it's simply a case of whatever comes along that I like, generally it needs to be cheap unless it's something special & I usually need to believe (or have the illusion!) that I'll I use it one day.... There is very little choice here in Southern Spain, most of anything quality that I've found has often got here along with a foreigner & all their possessions moving to sunnier climes, the chances of finding something like the Sargent autoset are nil to zero.. I did read your earlier post, I'm at page 36 & you've certainly posted some interesting reading as well as the other contributors, I've learned so much.
My woodworking has been very varied from green wood, draw knives & a shave horse, carving, handle making for chisels, forged & pocket folding knives that I've made, pretty much anything except fine woodwork therefore I haven't used planes as much as I'd like to.
I did get to do quite a bit of hand planing as pictured below though, a table I made during COVID lockdown, I wasn't working & there was a lot of used timber being thrown out on an apartment block being built nearby, door surrounds & pallets, etc....
The Sargent 422c was in poor shape when I found it but cleaned up pretty well & it was that and a newer Stanley no4 that I'd made into a scrub that did all the flatting from rough stacked boards, no power tools were used, that really was a workout.
