    Great collection - I wish you were my neighbor.

    Any idea what the purpose of the "Mod-1" is on those M63s? I have one that is dated 1943 so the "Mod" must have been going on from at least 43' into 44'.
    My guess is maybe there was some cost savings to be found in the different drive band.

    PS- my Mod-1 is available for trade if you want to enhance the collection.

    The only thing different on my Mod1's is a groove that is 0.090 inches wide by 0.020 inches deep in the driving band is gone. Seems like they merely got authorization to simplify the manufacture by removing one machining step. I have fired projectiles with and without the groove. It makes no difference.

    Thank you for the offer on the Mod1, Jeff. I don't really add 37mm stuff anymore. I have moved on to all the interesting things you can get out of Europe.

    I just noticed my 1943 Mod 1 is not threaded for a base fuze or plug.... yet it has the crossed cannon cartouche, meaning it was accepted as is.
    That's got me wondering...
    Are yours threaded?

    Nice collection and I bet the M8 and the 37mm field gun are a bonus too. What type of power load do you put in these things, not only is the collecting side interesting but the maintenance side and reloading would be fascinating as well. Do you use original reloading tools or are they specially made.

    I make the reloading equipment, and I have attached the link to my reloading video.

    It keeps getting larger. I have added a few cases and four projectiles. One is this M63 HE MOD-1 with a groove in the driving band. It also shows blue paint on top of yellow.

    I have three rather tatty examples as shown.

    As I understand it those without groove in the band are for practice
    and would be blue. But the first issues were with groove
    before the change was made. A yellow example without the groove
    I would question as to being a repaint.

    Finally found some information about the M63 Mod-1.
    In the book "Elements of Ammunition" written by Ordnance Major Theodore Ohart published in 1946, a velocity chart is given for 37mm rounds for the various projectiles, cases and guns used in WW2.
    There is a separate line for "M63 Mod (prac)". It is assembled with the MK1A2 case for use in the 1916 Sub-calibre gun.

    So apparently it was made specifically for practice.
