The 906 & the 921 were similar radios, and may have used the same accessories & battery box. But the Squadcal was xtal control, the Syncal is synthesized.

Looks like the TRA 906 Squadcal, but cannot see the front face of radio, that would have been better ??
If it's what i think it is then 18volts
Maybe wrong ?
