Second to the CTC15, the 630 is probably the most cloned set out there.
They made them for years, with a lot of slight improvements.

It has always been the belief that the 621TS came out before the 630TS, but if you look at original liturature and such you'll see that they were actually introduced at the same exact time. That is for sure. Other than that everything else remains a mystery with the 621TS. Why was it the only Vasso post-war designed in the old pre-war art-deco style? - Was it designed to be the '42 model update of the TT5?, ect.
