Need help with a 9mm kit for a fellow airgunnner

I have a fellow airgunner that paid for a 9mm conversion kit from over the Pond and never ever heard back from the guy.

So now he has a 9mm LW barrel, a Condor and no valve!

I reached out here had a few offers but my friend is not interested in spending anymore money after ending up with no kit and no responses to his emails.

Another good friend of mine has a full CNC shop, has a Condor, and is willing to help out a fellow airgunner.

I have tried reaching out here for parts so we can do testing over the Winter and provide ideas for our Forum Members but my emails have remained unanswered don’t know why as I am not in competition.

So what I like people to understand is my buddy has a business already that pays his bills this project is not there to take from anyone but a means to draw on 200k in machinery and years of experience while being a hobby to him.

Any design ideas for a 9mm kit including breech, valve, would be appreciated as I have only reached out here to fellow airgunners and nowhere else.

This fellow airgunner is unwilling to spend anymore money as he is not trusting many airgunners after being directed to this offshore tuner in the first place but my buddy is willing to invest time and material in order to help us all out.

Thanks in advance and sorry guys if I sound a bit off I am just feeling a bit frustrated here as a fellow airgunner has had a bad experience here.
