I guess some of the No8 trainers have bit the dust. Several heretofore unobtainable parts are starting to show up.
I have seen:
Bolt assemblies from IMA
Triggers and other small parts from Numrich.
I just received a very nice original handguard from Steve at enfieldteile.de in Germany
D.S. Solutions has upper bands in stock.
Be interesting to see what else will be showing up.
