Crestworth Astro Mini bottle top wanted

[Mark]

I don't suppose anyone has a bottle top and seal for a Crestworth Astro Mini they want to sell me?

Or if you have an empty bottle complete with top that would do just as well :)

 

I've been keeping an eye out on ebay for a while but no joy so far, I'm just short the last couple of parts to get my mini back in shape.
