The 1925 Sears, Roebuck & Co. catalog. Someone was perusing this catalog when they decided to order this very plane by mail.
The Fulton planes page from the 1925 catalog.
Here it is, 1925 Fulton model 5271 corrugated iron jointer plane. $5.10. Converted for inflation to 2020 dollars, that's $74.06. A bargain still today.
Would you have paid $17.50 + $25.00 shipping for this plane? If I had known how bad the condition was, I may have decided to pass. Still, I love trying to save the tough ones.
Here is what I saw on the eBay listing. Looks about average for a rusty plane.
The grime on the depth adjusting nut gave me some concern, but brass cleans up easily, right? Famous last words...
