you want a valuation for an Originall 66

It all depends on condition & and if it has had replacements piston seals,

I sold one to a fellow club member recently for £125.00.
it was in very good condition,and shoots good scores (in the right hands).

Cheers Bill i dont supose you have a downloadable breakdown of the rifle or manual ?
Im curious to see the pics of the internals to see how the recoiless system works, not that i want to touch it as im rubbish at taking guns appart ( get far too many bits left over )
Are there any shops that sell spares if needed ?
What pellets have you found that works ?
And are they possible to get to run at 12ftlbs ?
Cheers

I may have the original manual somewhere /
~I will try to find it for you.
~If you are not mechanically minded do not even think about taking your rifle to pieces.
I have done several, and they can be a real pig/ they either go together
first time, or seem to take hours.
The recoiless system works on the opposing piston method ,
one piston goes forwards with the opposing piston moving rearwards
creating a very effective recoiless system.

Similar to my Whiscombe then If you could find the manual that would be great.
And dont worry, like i said i wont touch a thing as it is defo not my strong point taking guns appart.
I just like to gather all the info on a item i buy to know how these things work.
Cheers Bill for the help.

Darren HERE is a breakdown of the Diana 65 which is pretty much mechanically identical to the 66. Chambers has quite a few spares but some are expensive. There is no possibility of increasing the power much beyond the six foot pounds or thereabouts it was designed to do.

Thanks for that Garvin, i cant believe this idea has not been taken up by gun firms and used for 12ftlbs.

The Diana version of the Giss recoilless system uses one active piston and one dummy/counterweight piston. Because just the one piston is used to generate the power there's no need for the pistons to move towards each other. To get 12 ft/lbs without making the gun too big, heavy and hard to cock, power has to be drawn from both pistons moving towards each other into a common compression space/transfer port, same as the Whiscombe does (did).
