Help needed spring advice

[merlin5oaks]

Hello everybody.I need some technical advice on airgun springs.

I am in contact with a specialist spring supplier in WEST BROMWICH.He has made airgun springs in the past but not for some time.He will make springs in quantities as low as 20 obviously the more made the cheaper they become.What I need is to give him as much info as possible IE how long how many coils wire guage wire tension and any other relevant facts for the various springs.And I am aware some springs will fit more than one model.If I can get these made to the correct standard and quality I hope to pass any savings on.if you have any information on any type of spring used I grateful.I will make this into a refference article for all to see.
I have a lot of tech info from the net but would like some personal opinions on the correct springs and spring failings.
Thank you M
