Hella KL 8 Flash Light Beacon 6V with blue lens

Rare Hella KL 8 flash light beacon for 6V in used condition. I tested the lamp with 6 Volt and it is working good. The blue lens is with scratches but without cracks or damages. The metal base is without dents. The chrome ring is without dents but little dented around the mount screw, what happens if the screw is tightened too tight. The chrome will be ok after polish with some age left. The motor is stamped with "6V" (top side) and Hella" (rear side). The base diameter is 22 cm, the total height is about 24 cm and the weight is 1960g. Made in Germany.
