I coul e-mail it to someone?

Hi J
Thanks for the correction. I have added the info to my small database.
From your dimensions, your SFS spring seems a bit heavier, but shorter, than some others.:
WEIHRAUCH HW95 19.6 13.6 3 245 31 Cobham
WEIHRAUCH HW95 19.8 13.6 3.1 270 Versandhaus
I hope the above is self explanatory. the Cobham and Versandhaus terms are where I found my information.
And to the post regarding Titans 13, 14, 15 .... my info only goes up to No. 12 so I would like to know as well if they do more.
Cheers, Phil
This is the spec of the spring in my new .22 cal HW50s from DB Shietsport Holland.
wire diameter 3,15
active coils, 28
inside diameter 14,25mm
free length 248mm
gap between coils, 6mm.
Both ends are finished rather than cropped and it pushed hobbies out at 695 fps from the box. Now it bits for a spring crop and the fitting
of a guide and top hat!
