LEICA E36, 36MM PUSH-ON RED ‘FIKYB’ RARE* INFRARED NO.1 & NO.2 FILTER NO CLAMP

Rare set of filter and very hard to find. These filters were produced over a short period and were replaced by the filters with clamps.I tried to unscrew the top of the dark to replace the dark by the lighter one, but I could not get it off.
Fit early 3.5cm, 5cm, 9cm, 10.5cm and 13.5cm E36 or 36mm diameter size lenses. But please be sure it fits your lens and that your lens has the 36mm diameter.Original Leica E36 filters are overall in good condition. Show hardly any signs of prior use. No scratches, no paint rub off. All the way to the side at the UV filter, the glass show two minute scratches. Furthermore no scratches, no cleaning marks on the filters. Comes in original ‘FIKYB’ box in good condition.
