There are bargains out there but it requires allot of ground work and being in the know I happened on my 1921 Lithgowwith matching serialized to the rifle 1921 Lithgow 07 bayonet & 1921 Lithgow double Stitch scabb by chance calling into a gun dealer who operated from home looking for Mk VII ammo and espied it on the wall as part of his collection.
It has in the white fore woods and still has grease in some spots but it has been fired think it got the new woods in 1943 the chap that sold it to the gun dealer had it from the WWII and had not shot it the gun dealer had it for 20 years and had not shot it and I have had it for 5 years and not shot it but I may next year.
It took me 4 years of slowly getting him to sell it to me for both of them $650.oo/AU which I though was reasonable but it was a chance the boonies is where you may uncover a sleeper but then again out there caring for weapons was not high on the farmers mind.
Whilst people are prepared to pay 2.5 K for in the wrap UF's the prices will remain up there, I look at Owen Guns site every now and then there is no shortage of 303's around just good rare ones like 1937's and the 5 1913 sent over to Lithgow!!! Well it costs naught to web shop and pine at what I cannot afford but am happy with my small 6 gun collection of which there are 2 jewels the '21 and my 5MD 1916.
