I think it’s the same 2 legged quad optic used on the S41/S41S
. I remember changing a bunch of them S41/S41S into triples because the optic sat on the LED pad and crushed the pad. Also when you tightened or removed the bezel you broke off one or both legs and sheared the domes off…sumtin like that…IIRC…
. ENEDED
. I have a bunch of them in the junk box I pulled out from the ones I changed out…
. I used one in a FW3A (had to add a copper shim for the height to delete the glass lens) to compare to the 10621 Carclo beam…
