Attached is a listing I posted here on 10/05/22 of ALL RU/GF and ALL RU-2 and later coil sets with cross references between units.

The coil sets of ALL RU-4 (1935) through RU-19 (1941) receivers are interchangeable, except RU-7, -8, and -15.  (Those three receivers use tuning capacitors with a 2:1 high-to-low frequency tuning range, while the other receivers have a 1.5:1 tuning range.)

I have an RU-16 receiver and was just looking at the coils sets I have on hand. Most are marked as RU-12 but three turn out to be marked for RU-17. As I understand it, the RU-12 coils will fit an RU-16 but the RU-17 coils will not fit. So if anyone needs these RU-17 coils, let me know.
