These very late School Test Blue Amberol cylinders (some are also referred to as Ediphone Standard Practice Records) have a few unique characteristics. They were factory released in cotton padded late style Edison Blue Amberol boxes, the plaster core was solid, the core was dyed a bluish purple color (kind of pretty actually!), the cylinders play at a very low RPM (this one plays fine [for me anyway!] at approximately 100 rpm!). I'm reminded of many of my earliest brown wax cylinders that play well at a very low RPM.
This one is #10 and features "ALFRED THE GREAT" as presented by Edwin J. McNamara. There is no lid. Honestly, I have absolutely no clue how to price this cylinder since I've never seen any sold anywhere so I took a shot in the dark at $150. Maybe it's too high maybe it's too low but that's what feels about right to me.
Please send a PM with interest. USPS First Class shipping is extra and at cost.
Thanks!
