Sorry, I've been a while. I've been working and not had chance to reply, plus I forgot to check the email notification box on my last post.
Fingers crossed, I may have sorted it. I googled shipping agent in Prague and then send 30 or so emails to everybody listed.
It's in transit, so fingers crossed I should have it on Monday or Tuesday. Downside is that it cost £190, so all money save on the gun has gone (and more).
Its going to be a long weekend waiting to see if it appears!
