These are irons for a plough (or plow over here) plane.
Here is a good example of one from Tony Murland's Antique Tools site. These are often found without a set of irons such as you have. Check to see if you have the plane. If not, you can probably find a plane for your irons. Plough plane irons had different tapers from set to set so usually a new wedge has to be made to match irons to plane.
I went to the viewing on Friday afternoon, looking particularly for some decent ash. None there - most of the wood there on this occasion was really pretty poor so I didn't go back to the sale on Saturday.
I did look at the tools, though, and amongst the usual stuff there were a couple of Norris planes to drool over, some Prestons and a particularly nice old Stanley compass plane, No.113, in exceptionally good original and useable condition. I'll be interested to see what they made when the results are published on-line in the next couple of days. Unless I continue to restrain myself I could easily become one of those c*******r types! :shock:
I noticed, too, just how many old tools had been totally stripped and wire-brushed or polished to a high shine - probably ruining any real value they might have had. :roll:
Alf, some of the irons are too rusry to see the makers name, I will get the wire wool out today and see how they clean up. The ones I can read all are Marples of Sheffield. The wedge to hold the irons is a replacement and one of the arms (correct name?) that holds the fence looks like a replacement too.
ps Dave, No problem about the change of topic, I was interested too.
