Yup, you'r right. Just checked Tiestes books, and the towers are on other Munich tinnies. Can't find this one in there at the moment. It's not under Munich or in the unknown section. However he has only 12,500 or so listed and I have a few not in there, so it must be a little unusual perhaps. Odd pin with the protcective loop broken/missing from the end, or is it just bent?
