I have a maroon with tan trim all weather bag but I can’t find one exactly like it on your site. One is close the R 51 Marble except mine has the green patch inside the same as you have shown but no red white & blue tag. Mine also is bigger 10″ wide x 6 1/2″ tall and 3 3/4″ deep. Also on my over & under the leather stripe down the front is not there just the leather and metal fastener. The inside looks exactly like the ones you have posted and it is maroon inside also. Any information you can give me would be helpful.
This looks like it was a very early model due to:
the green label
the double adjustable shoulder strap
the flat duck
and the unusual fastening tab on the front. It almost looks like a prototype. In the early days it seems like they tried many different shapes, closures, hardware, straps, snaps and interior pockets.
Back in the days this bag was made, there were no catalogs, or at least I have never seen any. So I can’t really tell you much about this bag except that it is a cousin to these two bags, one of which you might have already seen on our website. You can click on the photos to see more about them. They have some similar features to your bag but I’ve never seen one with the closure your bag has.
Maybe another reader of this blog will have more information.
