Totally agree Georg, problem with Knock ups in the UK, they gain providence on the circuit, Even a very reputable and famous gunshop on a famous range, have been known to knock up something and punt it on, a member here who has turned his hand to writing was on the receiving end of such a rife.
Other knock ups are passed through the auction etc, Desperate Dan mentions K98s, I,m sure you cringe when you see the crap some have knocked up and tried to punt it on through Scotarms.
As for the dealer regarding the L42,s I have to grit my teeth and avoid any mud slinging but his knowledge on firearms is about as good as mine on wild flowers.
He contacted me many years ago when he was with Jeff Organ regarding a knock up by The Late Chris Barber, a pile of crap I bought but was sale or return, asked on this forum about it and recieved the truth behind it, totally made up but the workmanship was abysmal to say the LEAST, was returned for a full refund, as that dealer was a true gentleman.
I told him all the info I had, but fell on deaf ears, they still went ahead and sold it, it had gained an extra 0 on the original price since I had it.
So if anyone here has a so called, yeomanry Light horse SMLE then you have in fact a item of someone's imiganination and the whole story behind it is pure fairy dust.
