Black Speedometer Sender Ohms Range

The early one is the range you've been quoted.
I seem to recall reading somewhere that the later style Smiths Sender is 240 Ohms empty and 20 Ohms full, in the opposite sense to the early ones.
Holden for example offer a generic Smiths sender: https://www.holden.co.uk/p/sender_for_s ... e_mounting
Resistance 237/273 at empty, 16/22 at full.
