Actually, I did all the leg work on mine, cause I got tired of seeing them on the MP, and not knowing what they went too...so i did a little chart that I could easily look up the filter based on the light...which filters would fit my C/P models, which would fit my "M3" bezels, and so forth.
Here you go Al/DaFab...Something like this...I could work on the colors to make it more pleasing to the eye, etc. The "Y" (Green) is a definite "Yes", "M" (Yellow) is it'll fit and function , but won't match, etc., and "N" (Red) is a definitly not compatible based on body/bezel/thread size/etc. This is just a sample, and some of the spot are empty (which is where I'll need your help Al).
I'll put the KX/KL heads in there, the weapon light switches, turboheads, and would like to go back as far as SF started there durrent model designation system. I would also do one for the weapon lights, and just post it as a seperate chart. At the bottom I would include all model numbers that fall under that for the new "sf" addicts trying to figure what category there light falls under. What ya think???
