Can somebody measure their 305mm g-claron for me?

I'm wondering about the lens' physical size. I would like to know how far out from the front of the lensboard the lens extends and how far behind the back surface of the lensboard the rear of the lens extends.

I really left a "please" out of the thread title. This simple little bit of information would be a big help.

Is this close enough?

Oh that's great guys! Thank you both! Where did you find that, Dan? I searched high and low for a technical doc like that and could never find one with physical measurements, only the more commonly needed optical measures.
