Maybe you look for comparision purposes at the Fuzz part schematic of the "Acoustic 360" and the "Benson 330H" posted (new) on my site.
Acoustic 360 uses a silicon for the first stage and a Germanium for the second stage.
For the 2 N 1306 you can use an AC127 or similar.
In principle the Orpheum is a copy of the early Mosrite Fuzzrite - you can find inside pictures and a schematic here:http://eu11.stripper.jp/pulcino/blog/archives/cat_mosrite_fuzzrite.html
also the early Guild Axis-Fuzz used the same circuit, inside-picture can be found here:http://www.electroharmonix.ronsound.com/gallery/foxey/foxey_lady.jpg
they only changed the input resistor from 10 M to 2x 10 M in paralell = 5 M.
All silicon version used the 100k (in series with 47k) in the collector of the second stage.
when i find some time i will write an article of this stuff with nice pictures.
The Orpheum Fuzz was also sold as the E.U. Wurlitzer "Fuzzer Buzzer":
