I doubt a whiff of co2 has done any harm.
You can soon check by filling it with air.

It probably had a small squirt of Co2 because Mark didn't have any high pressure air available and has a Co2 bulk fill setup.

I know a very clever chap who's initials are "L A", he repairs guns for possibly the biggest collector/ dealer in the country.

His primary focus is Co2 and self contained pump up airguns, but he repairs quite a few PCP's, (only for the above mentioned dealer) and he only has bulk fill Co2.

When he has repaired a PCP, he gives it a squirt of Co2 so he can test it. He has done this many, many times and guess what, nothing, the guns are fine. The dealer who sells them doesn't get loads of comeback due to failed O rings.

Co2 can cause certain types of O rings to swell up, also they can micro blister a little bit, but do shrink back to their original size. Personally, I've mainly found this type on Soviet Era Eastern Block Co2 guns, also I suspect some cheap Chinese O rings could be the same. The O rings that are constrained internally don't seem to fail prematurely.

Also there are one or two guns available that run on Co2 or high pressure air, dual fuel our American friends call them.

So, if I was buying this very nice Harper pistol, I certainly wouldn't be at all concerned about O rings failing.

Guys, thanks for all the contributions on this 'valuation' thread.

Thanks also to Ben for his excellent contribution with reference to the use of CO2

I have made all comments re value known to the owner, at the moment he wants to hang onto it.

I would keep an eye open for it at the next Kempton though
