Hello,
I came into possession with a Spiers infill plane and am curious if anyone knows more info regarding the time period in which this plane was made. Also, to what extent should the plane be cleaned? Posted below are close ups of the plane. In case the pictures are unclear or the markings are not quite legible, the plane iron reads, "Est. 1840(?) Stewart Spiers, Cast Steel Warranted, Ayr, Scotland." On the lever cap it also reads, "Ayr, Scotland." Eventually I would like to get some use of this plane. If anyone has any additional information aside from it's time period to share that would be greatly appreciated, as I do not know much about infill planes in general. Thanks,
