My leanings are toward Saba myself. Some of the older radios strictly for the German market may have only tuned to 100Mhz, though likely not many, as my Freudenstadt 7 had all the earmarks for European sale with the original Euro/continental plug on it and it tunes the full FM band- where it is denoted as "UK" I would suspect due to England having the full FM range as the US has. But that band that became today's FM band was denoted as the "FM100" band in the US into the 1950's. So you may see FM 100, but look at the dial closely.
They are a nightmare to restring, but the sound quality almost makes up for that.
