Nowadays, I think set names are unified internationally, but in the 1980s/90s sets often had different names for the US and UK markets. I think this was most prevalent in the Blacktron I and M-Tron ranges. For example 6923 was Particle Ionizer in the US but Cosmicopter in the UK. Even in this era set names were not typically printed on the boxes for the UK market, as the same packaging was probably used across Europe.
