DIY Folding Binocular Reflex Viewer

I'm planning to modifying my Sinar Binocular Reflex viewer into a folding one similar to the Horseman Folding Binocular Reflex Viewer.

My plan is to use the mirror assembly and binocular on the Sinar and make the body from aluminum of carbon fibre composite. I have done initial sketches based on the pics I found via google search but I still need to figure out how the mirror tilt mechanism works on the horseman.

Would somebody be kind enough to post or e-mail photos of the Horseman folding viewer (exterior, interior, tilt mechanism).

Of course I'll post sketches and photos once I'm done with the mod for those who want to do the mod themselves.

Thanks in advance.

P.S.

I've posted this query on another thread here in the forum but thought it might be better to post it on it's own thread.
