One slight oddity, we usually see these Carltons with Raleigh bottom bracket and octagonal head set 26 TPI. Here we have the RH bracket cup with a flange, so not Raleigh. The 7 figure number automatically stamped on the bottom bracket makes me think of perhaps a large far eastern maker. The number on the fork end is more like a Sun in style.
After the demise of Worksop did Raleigh source frames from the far east?
