The City Opera thrift store, as of last night, had ~ 6 Cleverlys. I am guessing they are about 9.5-10. I wear an 8 to 8.5 and they were big on me. They had markings, but not really a size marking as I would be familiar with. They are all used, obviously, and could use a polish. May have bben more used than some would prefer, but, were also under $50.00 the pair. They had brown suede, black suede, brown cap toes, and a black cap toe.
As a bonus, there were ~5 Turnbull and Asser shirts - I would say about 15.5 or 16 by 35. The sleeve length was fine for me, but the neck was too tight and I am a 16.5 x 35. There were an assortment of cuff styles and shirts were striped.
