All VHF / UHF receivers of Eddystone's 1990R receiver series were equipped with 250 kHz L/C and 30 kHz crystal IF filters as standard.
There were some different filter complements available on special order:

Eddystone 1990R filter options
Option A:
250 kHz + 30 kHz + 15 kHz
Option B: 250 kHz + 30 kHz + 7.5 kHz
Option C: 250 kHz + 15 kHz + 7.5 kHz
Option D: 250 kHz + 15 kHz
Option E: 250 kHz + 7.5 kHz

Crystal facility or synchronizer (frequency synthesizer) use recommended for use with 7.5 / 15 kHz IF bandwidths.
