Thanks. Yeah, I've seen many like you said with the single brace in the rear( including catalog images), and some with the double. Still hunting I guess. I'd like to see a pics of your Falcon.
My Blackhawk is currently not put together as are about half of my bikes. The picture attached is how it looked when I purchased it. It had been setting in storage for an unknown time to me, and had acquired some peppering on most of the chrome. The clad wheels were toast.
The chrome parts have cleaned up nicely and I have acquired another killer set of clad wheels and the rest of the correct parts for a 34. = the unique “Elgin” pancake horn with flipper switch mounted to the handlebar, and a nicer seat, NOS stainless fender set with correct braces. etc.
