I’ve been reading through the thread & am at page 17..... So I’m about 10 years late to make relevant comments!
Firstly I’ve been living in Andalucía since moving to Spain in 95, my work has always been with my hands & for many years oriented towards metalwork but over the last 10 years or so have become interested in woodwork & carving.
I (like many on here I presume) was collecting tools years before I realised I was collecting! One of my interests that stemmed from rummaging around fairs & Flea markets here in southern Spain was very old tools & implements, the older the better & especially wrought iron, but my collecting is very varied & planes are a part of it.
Back to the thread, page 10, reply #143, johnsironsanctuary shows a sad old plane missing it's horn reminded me to drag out my wooden planes (I'm moving property & in limbo so lots of my things have been stacked up in storage way too long) which is no bad thing as they need cleaning & the irons need oiling before they deteriorate any further!
I'll maybe find out what happens to johnsifonsanctuary's old plane (no spoilers please!), but I would consider it very old, the iron not necessarily being a repair but having originally had a forge welded steel bit on the iron when carbon steel was precious & in short supply, I imagine the rest of the iron is wrought. I'll not comment on my feelings about restoring it till I read the outcome.. or not.
The images show an oak plane missing it's iron & wedge also in a bad state, I've put it here simply because it's hard to believe such a piece of wood would ever have been selected to use, the grain runs in line with the throat, the pictures speak for themselves including the epoxy!!
Given to me to use to make "a wooden wood plane plane made from a plane that won't plane"... But decided it was too rough!
