Hello!

Will the reverb transformer 022921 (old vintage) work with the 3-spring reverb tank 9AB2C1B?

Both are vintage parts, made in america.

Probably, depending upon what model of amp and whether or not that reverb tank is compatible with the circuit's specs -- specifically the input/output impedances and the grounding scheme.

That seems right for a Vibroverb, 8 ohms to 8 ohms.

The OEM reverb tank in my original '64 Vibroverb measures 0.81Ω at the input and 82Ω at the output. It's equipped with the 125A20A reverb tranny, which correlates directly to the newer 022921 Fender P/N. If your reverb tank's specs are similar to the input and output impedances of mine, the tank *should* be compatible with the 022921 tranny.
