    On the Hyscore summary;

    "It is interesting to note that he was a skilled engineer, but obviously was quite happy to cut corners where it did not really matter, as exemplified by the crude trigger guard"

    Looks like a normal Hyscore trigger guard to me, pretty pants bit of bent tin



    He obviously liked that bit at least!

    On the Hyscore P/Type .......is it a phillips screw (not posi) by the way on close examination,as can't see from the photo.

    As obviously Phillips are used (amongst on other things) widely in engineering, for example on engine cases (Japanese) and by many motor builders including General Motors (since 1936 ).

    Also one of the standard drives in Aviation (NAS series), so are far from a bodge / cut corner if this type, despite looking less "gunny" than slotted jobbies.


    It almost looks like it has writing on it (the cross head in the Hyscore photo) just as say NAS 7400 10/32's (random length plucked from memory) and others of this ilk do, but it might also be a trick of the light.

    Can you make the pics bigger / have a dekko?

    The coding is not industry std. but a quick way to determine grip length / thread size, different makers mark the heads in different ways, but below is an example.....
