this cant be 1950 as regs In the early 1950s, as numbers started to run out, the components were reversed, giving rise to registrations in the format 123 ABC. in 63 As a result of this, the Suffix system was introduced, a letter indicating the year of registration being added at the end of the plate, which until then had comprised only 3 letters followed by 3 numbers.
Thus, 1963 plates had the format AAA 111A, 1964 plates AAA 111B and so on.
1974 I make it as there was no I it looks like 1.
If I not mistaken this is SS50cc Honda and with the high silencer it has to be after 1970
And not don't like it it well over PP just look at the artefacts and colours...
