    Which system are you using for the bomb markings?
    Pre '44, '44 - '48 or '48 - '51? They are all slightly different.
    The bomb bodies were originally coated with lead free copal varnish and baked. Repaired bombs were shellacked
    The bands are not varnished, but treated with lanolin to reduce friction on firing and prevent rusting in storage.

    Thanks for the BB identification in my thread.
    The Aussie 3" mortars I had (12) were all varnished completely including the bands. Made by J&W 4/45. Why different to UK ?

    Having dug back to a 1942 reference it says "bombs are varnished" with no reference to bands.
    The varnish is that thin and baked, I doubt that there would have been any residue in the mortar barrel.
    The first reference was 1953, by which time quality control and more time, would have come into play.

    I think pre-1944. It isn’t clear, but I think there may be a ‘40’ stamped on the body.
