Looks like this frame, although with a different fork: https://chinertown.com/index.php/topic,3739.0.html
Definitely not. Look at cord length of the head tube. It's massive on the BR frame. Also long smooth curve of downtube towards headtube vs angular.
Looking at the photos I was expecting a slacker head angle. But geo table is saying only 71.5. It looks like more ... I wonder if it's correct. IMO it needs more given the length of the TT.
XL also absent.
Tire clearance looks massive, assuming there is sufficient lateral clearance at chain / seat says and the fork. Assuming there is, height wise you could probably fit a 52-54 on the rear and a 57 on the front.
