Hi, does your Windsor Pro have any drilling’s or openings in the bottom bracket? What size do you measure from seat tube, bottom bracket center (or dustcap of crank) to top of top tube (CTT) and to center of top tube (CTC) plus the length of the top tube, center of seat post to center of head tube?

what type of bars and stem does it have?

Additional pics would be helpful. Thanks for the reply.
