How many Long Butt Stocks

Just wondered how many No4 or SMLE rifles came out of the factories with Long Butt stocks and if so are there any originals still around.
If not, is there anything around to help with matching wood type and colour to an existing rifle, or is it just a case of finding a Long stock and making it match as best you can?.

Both model had long butts as an option. You don't see a lot of No1's. No4's a lot more plentiful. Best is to put a picture of your rifle, identify the wood and see what you get offerred for a long butt.
