Hi Jeb,
Someone suggested a '36 L-4 - I have a '34 L-4 (F-holes) which I got from Archtop.com in Seattle - it needed some work as the frets had been filed almost flat but after an excellent refret - it plays fine. Tuners are a bit tired. It's a lovely old guitar but I can't help but feel that there AT-16 would beat it.
I also have an Eastman AR805e which, frankly, is a tad better/louder sounding than the Gibson.
However another luthier that you might lke to consider is Daniel Slaman - who makes a highly regarded version of the 1923 model 16" L-5 - see this:

His price seems to be 8250 Euros = $11,350 - plus shipping and whatever import taxes the US might charge. However he has a stock item selling for Euro-7450 ($10257).
In fact if you look at his YouTube channel he has filmed the entire build.
