If the 22.5" is the official Raleigh size, the frame could be a bit smaller than most people would measure it. The Raleigh measurement back in those days was, as I understand it, to the very top of the seat tube, a bit above the top line of the top tube, maybe 5mm or so. For example, I'm 5' 6" and a 21.5" Raleigh International is quite fine for me. When I go to measure it, it comes out to a small 54 cm, ctt and maybe 53 cm ctc. So, that 22.5" Raleigh might match up to a small 57 cm ctt or about 56 cm ctc. So, yeah, it would probably be a bit small for you
