Just measured the spring that was in my Mercury when I got it:
Wire diameter: 3,2mm
Inside diameter: 14,1mm
Number of coils, counting both ground end coils: 34
The gun came to me with this spring, and the gun had been worked on previously(attempt at barrel replacement plus new guide fitted), so I have no way of knowing if it is original from the factory.
Don't know Guy but would like confirmation. Thanks Evert. No note on length?
I bought a batch of springs from Vic Thompson a couple of weeks ago. amongst them is one in a sealed plastic sleeve marked 'BSA MERCURY' and an indecipherable part number.
Measured through the sleeve as I have not opened it. Length 265mm , ID 14.7mm , OD 21.11 mm . wire diam 3.31, Number of coils 32.
All the measurements should be close to correct but on the large size for tolerance
WW that's brilliant. Thanks again both.
If you find a supplier for the original spec please could you publicise? I got some off knibbs a while ago but they were a similar spec to a titan but without the black coating so much wider pitch than the originals and hence stiffer.
