Identification infill plane Rotherham Coventry K28

No help here on an I/D, but a gentle clean couldn’t hurt..

-- Glen, B.C. Canada

I am willing to bet it was made by a industrious craftsman. Little things about it make me think that. The fact that the infill is 3 pieces of wood and not one the shape of the lever cap knob it was clearly a brass bolt. The unfiled peening near the adjuster.

How are the sides joined to the bottom? If you study that edge carefully can you see any indication that they were two different pieces joined together? If not then my money would also go on user-made. The length would indicate something along a Stanley #8 with toe and heel chopped off – but the width 7mm comes out to just over 2.75” and a Stanley 8 would have been slightly thinner than that so maybe a British equivalent – record or ???

Well, thanks for your support. Did a little cleanin. It was more of a dedusting, so very gentle.

I found out, that there was or is a company rotherham that made some brass oilers.
So someone might have just used some spare brass parts with the names on to make the adjustment knob.

The sides are joined with 5 dovetails to the bottom. 10 screws to each side.

So it is probably British.
Any guess on the age?
