Mate, paying close to $400 US dollars for a backglass incl shipping seems too bloody expensive for my taste, on principal alone.
I am sure there is a translite repro like all the new translites out there for around $100 US plus perhaps $35 shipping.

* I shall try n pull a rabbit outta my hat and speak to two people i know, One in the USA i met on a forum who sourced my Viper Glow balls and another guy I know in Europe. $400 is too much Beaky.lets see what the other guys come up with.I shall look for a rabbit and a hat to help out too.

When it comes to this pin mate nothing is to much.
I am toying with the idea of a bk2000 gold.
I will photo shop the gold side rails and lock down bar and legs and will see what it looks like.
as you know this is my holy grail of pins.
I know it might sound mad but when you love a pin as i love this one then nothing is going to far.
