No, it's stamped on the interior lining, except the "P", which is handwritten. I agree, that votes against the Masterpiece designation as does the rubber sole. The captoes, of course, have the Masterpiece oval. And too late--I've already looked on the websites for something similar. The closest thing I've seen is the C&J chukka that Ben Silver sells (also rubber soled). The leather doesn't appear to be particularly dried out. I wanted to take the pictures before I applied anything to them.
I was simply guessing about what the handwritten "P" meant. On a recent trip to Bennie's, I saw a much cheaper looking loafer that was numbered in the 8000's, but I doubt that it was a Masterpiece; it had no oval and no "P." I think the oval is the most reliable guide, but as of yesterday, I again saw, on the rack, what I am 99.9% sure was a Grenson shoe, in an 8E, with the label, "La Coronnerie Anglaise, Paris." It was an plain oxblood monk strap with a punched toe (somewhat like the toe on the C&J Weymouth). It had very different numbers, no oval, and an entirely different sole, but still looked like a very expensive shoe to me. It could be that Grenson makes other lines for private labels, completely different from its Footmaster and Masterpiece series, but of no lesser quality than the Masterpieces. The "Henry Maxwell" shoe was somewhat different too (and it was marked "second") but it had the oval. Ken Pollock P.S. Buying from this lot of shoes is like treasure hunting; who knows what is to be found there. Let's not forget the prior post by someone who bought a pair of "Shipton & Heneage" shoes that had come to Bennie's with the batch of Grensons. The consensus here was that that shoe was made by Crockett and Jones. It seems clear that Bennie's bought a somewhat mixed lot of English made shoes.
