The son-in-law was recently at a charity auction that featured a T-53. He texted me and asked what it was worth. I said nothing as an original. The auctioneer actually announced that it was a knockoff and the sale price was a reasonable $150. I hope that the buyer doesn't try to sell it down the line as an original. They are everywhere.
I'm out of town and don't have my educational T-53 photo on my laptop or I would run my add on ebay again. Somebody else make one up and post an ad on ebay. In fact we should have several T-53's of different styles posted. I know there are some creative members here. If you design a T-53 and don't want to post on ebay send me the photo and I will. Here is mine from an oldgas photo.
