Agreed Jim, unfortunately, here in the UK, you really need to dot the I's and cross the T's with these things ... Make sure all the legal requirements are rigidly applied.
The gutter press (all of them from what I can see) would have a field day otherwise.
"Machine gun parts dug up by gun nuts shock"
Or a rabid variation of the above, perhaps including the word assault, the usual dreadful pathetically poor journalism the UK excells at these days...
I see an Enfield rest, Bren breech blocks, Bren Drum Mag and winders, Sten Mk2 Barrels, Bren Barrels, Browning 1919A4 barrels, a Vickers Barrel, Sten butts, Enfield parts, 07 bayonets.......
I dug there with Steve a few years back and got some nice Lewis Handles as well as some Vickers, Bren and Sten parts. One of the brass but discs was numbered 177 and this is now fitted to my Inglis Bren serial M177 which had the disc missing.
