IMA still has the Brit canvas holsters in stock,,originals,,both the RAF light blue color ($25) and the G/I Khaki color ($40).
More than they were but that was then and this is now.
A quick glance at their offerings didn't show any of the ammo pouches, belts, etc for the revolvers..
Most everything else they offer now is repro leather with a few orig holsters & belts here and there.
Their ad info states the above holster(s) will fit a Hi-Power or a 1911 as well as the Enfield 38 or S&W 38.
I thought the latter two were what they were made for & issued for.
I seem to remember a separate sized canvas holstera was made for the first two.
But I could be just mis-remembering.
I may have some 38-200 Brit Military,,I will look.
I know there is some .455 in packets there somewhere in the pile.
I used to shoot 9mm Browning Long in an Enfield 38.
Norma brand, FMJ commercial 'White Box' ammo.
Kind of snappy to shoot in the Enfield as I recall but it took it in stride
It was cheap at the time. $4.50/box of 50 if you bought a case.. & w/ Free Shipping! That from CAI of all places.
I still have one box left.
