The serial range of swjXE seems to grow every year. In the last 10 years or so since they appeared to come out of nowwhere, we have seen at least 1 a year. The range is now from 5500T - 6500T, and I expect that range will grow over time. I do try to collect all of the ones I see, but I know good and well some are discovered and hidden away in collections, as a few I've recorded almost made it by me without any knowledge. I know that because of that there have been more than I see. If you ask me, nearly every single one made came back to the US through souvenir hunting GI's, and more are out there. Its incredible that they have not been seen before- I think they have for the last 70 years, but have been classified as postwar by the collectors that saw them, maybe even misread as svwMB since the French guns are so well known. I do call them rare, but these are not unobtainable. If you can find one in the rafters of a house, or one just randomly pops up in a local estate auction, they are out there in number. We all just desire one so bad we feel they are unobtainable, but I know people who have obtained them with reasonable money. That first auction of 20k still haunts the internet searches which also spoils the conversations about them.
