Except for the dimensions and delay, the Base Detonating Fuze Mk 28 is like the Mk 19.
The fuze will function on 1/4 to 1/2 inch plate and on water.
The special "green stripe" Base Detonating Fuze Mk 28 was issued for major caliber HC projectiles, but is being replaced by the Mk 39.
Mods 0 to 14 represent different manufacturers.
Mods 15 and 16 are identical to earlier Mods, but are fully moisture resistant, with a silica gel capsule in the auxiliary detonator plunger and all external joints coated with bakelite varnish over a lacquer base. Mod 17 has an additional booster charge.
No information about functioning.
No information about hazardous components.
Nothing else to see.
