Okay, this is just from memory, so I can't vouch for its validity, but...
I don't think they sold the Misser Rep as a full bike, just a frameset. So, there's no such thing as an original spec. Even in the pics you've posted, there are at least three different builds: one with the Z1 Bombers, one with pre-production Boxxers and one with Judy DHOs.
If I was building one up, I'd be looking to spec it with high end DH kit from the period, but not worrying too much about what was on a particular individual bike.
Yeah I realise that I posted some different specs, I also can't remember if they sold the Misser as a full bike but if they did I would of thought it was the one with the z1's.??
But as the original owner told me it was bought as a ex uk team bike I'm guessing that would be the same build as the lower 2 pics I put up with Scott boumont riding the bike.?
Also if you look carefully the shock on the bike Boumont is riding is the same as the one I have on my frame and I also have the same MRP chain device as the one in the picture that came on my bike when I bought it.
So I'm gonna do a bit of a mix match spec I think.

XTR 950 cranks

Thank you to everyone who helped point out the spec.
