There's something amiss in that logo stamping...
They didn't mark them with a group size until the beginning of the 1990's. Looks like it may have been graded a Tilshead (a second) in which case the stem would not have been marked with a JU logo. The staining matches the reddish tint that was applied to Tilshead grade pipes.
A Tilshead would not have been stamped "J Upshall". The company was Tilshead Pipe Co. James Upshall was the branding of their top grade pipes.
I suspect that this was a pipe that was made in the late 1990's or after. I have never seen a "J Upshall" stamping on a James Upshall pipe. Pipes that were made in the late 1970's/early 80's were stamped by hand "James Upshall" with an oval border (more like a capsule shape); sometime around 1981 they were stamped with the same stamp, only the impression was deeper, as they began using a stamping machine they got from Sasieni. In late 1983 they began engraving the logo using a Hermes engraver.
The "J Upshall" stamping you see might have been due to some of Moti Ezrati's "underhanded" business practices...
