Coil built Salt Pig. Impressed ?R - Louis Hudson?

A large, heavy, coil built salt pig with impressed mark. Last letter looks to be 'R' but the first could be 'C', 'L' or none of the above.
Any ideas?

Maybe a Louis Hudson mark?

Now that would be ironic, given my green "LH' pot that likely isn't a Hudson piece.
Oddly, the two pieces were pulled out of seperate boxes last night as I was having a look through some of the many boxes in my loft with a mind to actually identifying and cataloging what''s there. The boxes haven't been opened since I put them up there 10 years ago, and some haven't seen the light of day for up to 20 years. I literally just opened one box and took the top newspaper-wrapped pot, then did the same with another box, so what a coincidence that Hudson's name has been mentioned in both cases.
