[GreenKeys] Another What's It

[W8MAQ@aol.com]

Hi again TTY'ers,

Here's another device from last weekend, picked up at an SK's house with 
other interesting items. There's a picture at:

There is a brass tag on the front right that says FRXD10EP338SPL

I know I've seen a picture of this thing while surfing, and it appears to be 
a typing reperferator, but the mechanism at the front left is a puzzle to me. 
There's also a 33-pin Jones plug at the rear. Is it 14-series equipment or 
15? Or other?

Although I'm obviously new at TTY, thanks to the collective wisdom and 
knowledge here, freely shared, I'm learning quickly. Thanks very much.
