Hi chaps,
Following on from Jim Tyler's excellent and thought provoking thread in this month's Airgun World Technical Airgun Series relating to the merits of longer, narrower gauge mainsprings, we thought a thread listing the specifications / dimensions of numerous mainsprings would provide a useful reference point.

If we can compile enough data for different springs, this thread could then be transferred over to the Useful Tips section, providing a handy reference for future use / comparison.

So, if lots of people could possibly contribute, this would provide a very useful database for various different springs. This would provide the option to experiment and also to match a spring to a gun, once internal dimensional requirements are known.

Details required ( please feel free to include as much information as possible, especially if I've omitted anything), please provide information such as:-

Make of spring, eg V-Mach, Titan, Vortek, Maccari, standard fitment etc.
Length
Pitch
Number of coils
Outside diameter
Inside diameter
Spring rate
Wire diameter
Known fitment applications

Jim, please feel free to edit/alter as desired.....

Thanks in anticipation for all your help/input.
