Here is a photo I took after arrival, much more obvious what the first clue was that made me look hard at the auction.
I forgot to bid on it and the auction ended with no bidders. Fortunately they relisted it and I bid that time. I won the auction with no other bids. About $100 is a little high if it was just the 3446 mentioned in the auction. It's a great price though for a nearly complete 3446 and 3445 - with the 3445 Guard Tower being complete with the hard to find balcony, bell, and bell frame pieces.
I had to bleach soak a lot of the parts to get the brown color knocked down, but they mostly came out fine. A few are still brown but not any significant ones. The tower will be making a cameo appearance in the upcoming Marketon Joust. I really like this tower, more than I thought I would. Int he end, one of my better eBay buys for certain.
