Don't give up on it. You may come across someone who wants to sell theirs and doesn't know what they have. It's not unethical to simply pay the asking price.
I've been fortunate enough to pick up a few nice rifles for reasonable prices, even when the seller could have gotten more.
One nice gent who sold me my 1950 Long Branch No. 4 Mk1* noticed it was close to my birthday when he was inspecting my PAL. He smiled and handed it back while wishing me a "Happy Birthday!" It was, I was elated to find an Enfield in such good condition. Like my 1935 Brazilian Mauser, all it really needed was a good cleaning and some oil.
As it was, he was responding to a WTB ad I had put in the Buy&Sell. He could have gotten a few hundred dollars more for it, but I think he was just glad that a rifle he had no use for was going to a good home. He said a neighbour gave it to him for free, so he didn't do too bad.
Here's a list of the rifles I keep an eye out for in mint, or at least, very good condition.
M1935 Brazilian or Chilean Short Rifle in 7x57mm
M1941 Portuguese Contract K98k in 7.92x57mm
Czech post-war K98k in 7.92x57mm
M1950 FN Mauser in .30-06
No.4 Mk2 Fazakerley in .303 British (with blonde beech stock)
I remember seeing a Fazakerley still in the wrap at a gunstore in Kelowna. I scoffed when the owner told me the price, I think he wanted $200 or $250 for it. At that time, full wood No.4 Mk1's were going for about $100 in decent condition.
If only I had known then what I was passing up...
