Grover makes one that looks like those- these are black, but they're available in chrome & gold. Their old tuners look exactly like the ones in your photo- the ones on my '70s SD Curlee are the same, in gold. The ferrule in your photo makes me think they're Grover. https://www.grotro.com/Grover/BASS/T...nes-145-Series
Are you replacing one that was damaged, or are they hard to turn? Mine were pretty tight and I completely disassembled, cleaned them with mineral spirits, lubed and reassembled them- huge difference and they're just about "like new". Well, other than some worn plating.
