Not all JJCO were junk or bitsa's. As with any rifle, you have to carefully inspect and do your due diligence. I've made my share of mistakes and have a box of worthless "collectables" to prove it! 
However, I also have a 1941 JJCO Mk III Lithgow that is a great battle rifle with the magazine cut-off and the original barrel. Numbers match bolt, receiver, barrel, sight and nose. No number on the forestock. No FTR marks but at some stage it received a new bolt, which was numbered to the rifle - I don't think JJCO did this. Head spaces correctly (using Forster Field & Go gauges) but I have not fired it. Barrel is dated 3 '41, receiver dated 1941, stock dated 1941.
