Original small smoke colored optics lenses with a threaded trim ring. Like the other lenses, I have given up on attempting to figure out exactly what they go to. These are new old stock from a warehouse with wear and dirt from age and storage. Price is for 1 lens. The thread appears to be approximately an M24X0.5 so if your optics have a fine threaded hole that measure about 23mm across (24 -.5 -.5=23), then this is probably your guy.
Please only measure by the metric readout on the calipers, the standard side of this set is of a bit.
