[MILBRO] mod.51 / series 70 spares wanted

[Hu hellaxe]

Have one of these larger youth air-rifles which [Dennis Hiller] writes was perhaps an export-only* model and in his book [collectors guide] states was a rather fine latterday product of the [milbro/scotland] concern.
this mod.51 is threaded for a can and there is no pre-load on the factory mainspring but action will not cock/ fire due to entire safety-catch mechanism missing (only large allot trigger extant)and would appreciate any help here to get this unusual nr.2 bore airgun up & running once more. regards. Hu hellaxe
*have seen [milbro] G76 "PERFECTA" model with handbook in german- ;no longer have this airgun but should be delighted to swap for other [ milbro] or [haenel] ephemera, w.h.y.
