Looking to buy this bike and I'm interested in what it is exactly.
Seems pretty straight forward for the most part: "R" - Reynolds tubes, "E" - built between 1981 and 1984, "5" - size 55 (please correct me if I'm wrong).
But the last stamp is throwing me off, is that an upside down "P" for Panasonic or something else completely?

Interested in what the experts think . Many thanks in advance!
