Tropical set of Gasmask Spare Lenses

Tropical set of Wehrmacht Gasmask Spare Lenses (Klarscheiben Tropen). Still sealed in their original square (6,5 x 6,5cms sized) metal container, closed with black sealing tape. The container is marked with 'Klarscheibenbüchse (TP)' and maker marked and dated 'hrr 1942'. These are often missing pieces and perfect to complete your gasmask set with. Nice original set in good unissued condition! I've found an original carton sleeve containing 50 sets in good unissued condition, you will get an example as shown of my choice.
