Great patina right out of the gate!
Be careful not to get too aggressive with cleaning it. You can always remove a little more but you can't put it back once it is gone. At least not original patina!
I do see the difference in the fender braces but I'm not familiar enough with that era of bicycles to tell exactly what I'm looking at. It's a fun exercise trying to figure it out though!
Stainless or aluminum fenders?
BTW, I like that filter that you're using. That would make some great looking posters if the car in the background was removed. :cool:
