There was a mount like that for sale on ePay earlier this year, and there was a discussion about it here. I cant find the thread, but i did find this pic on another website. From the details, the owner was putting together No 4(T) clone. I believe this was the same mount that was for sale earlier this year. Very similiar to the set-up deing discussed here.
I post this only for discussion purposes, and not to offend or irriatate anyone.
