A Bird 43 wattmeter uses a 30ua meter movement

The Bird Inline wattmeter used in broadcast transmitter applications uses a 100ua meter movement. This type of wattmeter uses the external 1 5/8", 3 1/8" and larger line sections with the external 100ua meter in a separate housing.

I have no idea what the meter in a Simpson 260 is....

A Simpson 260 VOM has a 200 ua meter. Maybe find a broken 260 with good
meter movement? An old Bird inline wattmeter with remote meter has 200ua
meter also. Good Luck.
