Here is a shot of the most recent pieces I acquired. Thanks to many Yankee Polecats at our swap last week, I was able to trade for many of these. The foreign pieces are unlisted (to my knowledge) and the white piece originated from France. Although the brown insulator looks common enough, it lacks an inner skirt and doesn't resemble any style in the book.
The domestic pieces include a U-317 Square D, wonderfully glazed U-263 and a really heavy, thick U-133.
Thanks for looking and thanks to all the Polecats for making such a great day possible.
