I should have pulled up the Smilies menu and added a few winkies!
I need to pare down my herd. But I have come to the conclusion the '66 P-13 25" is a tad too big for me. Here's the link to Harris where I bought my TA

What was hard was finding the big ring. I wanted to avoid dealing with Mr. P White, even though he's all of 20 miles from my house. He is so disagreeable. Eventually I found a 50 tooth on ebay from a seller in England. He was less then Mr. White even with the shipping.
