Decades ago I got a box of TA pieces along with the purchase of a Paramount, but never the right pieces to built anything useful. A number of years ago I sold all the arms on ebay, but kept one pair. A couple of years ago I bought these outer and inner rings at a swap meet with the thought of finally building up a double. A week or so ago I said what the heck, and ordered a new triple ring and the correct bolts to build this up from Harris. I'm planning on putting it on my next build, whatever that is, with a Nuovo Record rear with a Rally cage and a 14/34 freewheel. As these arms are 185s, should be a hell of a climber! Oh, ran these arms and rings over the buffing wheel!
