Funny you should say that: the BAR and the desire to own one was the reason I got into collecting. Still haven't found one but a bunch of other cool guns instead. The BAR is my holy grail
I had three, a Marlin Rockwell, a Royal Typewriter and a NESA. The MR was the nicest, about new and not overstruck from it's original 1918 model marking. Still had the wood butt too. I completely understand.
They all sold through time. The Royal Typewriter was sold to one of my soldiers back in about '86 or '87. The Marlin Rockwell sold about winter of '92 when I realized I had too many really neat guns and no house. Last to go was the NESA in about '98 after everything else almost had gone. It wasn't perfect so I thought it might be hard to sell...not so much. The Marlin Rockwell was really sweet. Wooden buttstock and original markings of 1918. No overstrikes. I had full EIS for all of them. Mag chargers and clips, mags and belts. I still have a BAR sling in canvas, longer than the M1 sling by a couple feet. That's the only scrap left of all of them...no pictures either.
