What can you tell me about my two-channel Dual Rec?

[automattack]

Serial number: R-014701
Writing on the inside of the chassis looks like it says "V34/00"
There's writing on some other parts that I can't make out except for a "G"
Large logo on the front, knobs have little indents instead of pointers (for lack of a better way to put it).

There are a few pictures of the inside at http://imgur.com/a/Sj4G3#kIUBGnB
I'm willing to take more, or peek around for other clues...

So I'm guessing it's a revision G, but what does that mean? Is there a site with a comparison of the different versions?

Thanks.

A revision G is the standard 90s Recto sound.
