The Bird 43 was introduced in 1952, and is still being produced/sold today, largely unchanged from its original design. These meters are basically the While this meter does not measure VSWR (voltage standing wave ratio), you can determine SWR from the forward and reflected/reverse power readings.

BIRD 10043 THRULINE SWR RF WATT METER IN GOOD CONDITION HAS SOME MARKS AND SCRATCHS AS SEEN IN THE PHOTOS MEASURES 115x70x100mm 26-30Mhz POWER RATING 10 WATTS TESTED AND WORKING 100% COMES WITH SPECIFICATION SHEET THERE IS NO ORGINAL BOX BUT WILL BE WELL PACKED FOR SHIPPING The Yaesu FP-8 power supply with speaker delivers 13.8 VDC at 8 amps. 1.13 at 50 MHz. Two 50 ohm dummy loads in parallel should give an SWR of 2.0. I get just over 1.85 at both 28 and 50 MHz, good enough. However - If you are using the meter for power levels of 600W or less, then I would recommend that you change the transformers to 20 turns.
