Here's those shots Swindy:

Unfortunately the bag strap is sewn onto the bag on one side as shown above. I cut it off with about an inch spare, folded over the extra inch and then sewed it up with a D-ring. I punched a couple of leather rivets through it just to reinforce my inadequate stitching as seen below.

The other side already has a loop, you just snap the metal slide off and the strap comes out. Slide a D-ring in, and add your strap.
The interior is somewhat lacking in the compartment department (gee I'm a poet...) I wouldn't really trust the strength of the white divider, but then you get what you pay for. I used some old saddlery leather I had lying about for the strap
This is it in action (and my fed). The buckle has slid all the way down in this pic, simply because I didnt have enough leather for the proper 65" strap, so the buckle is really only there for decoration. My leading lady's bag is a claymore mine bag, with a similar strap attachment.
