From looking at various articles about Sorkin instruments on the web, Sorkin began by sourcing quality instruments and sometimes helped to develop new lines of instruments. Sorkin always seemed to be close to the cutting edge in the musical instrument field, if not at the cutting edge. Sorkin got on board with electrically amplified guitars early on, including developing a line of tube amplifiers through a subsidiary called Multivox. One of its lines was Premier amplifiers (which supposedly introduced the first piggyback amp, usually attributed incorrectly to Fender). http://www.vintageadbrowser.com/music-ads-1960s/42 (Scroll down for the Premier piggyback amp shown next to the Cannonball Adderly record release notice).
The Sorkin ukuleles were endorced by Bobby "Uke" Henshaw and claimed by one web site to have been "made in Sorkin, N.Y." The early ones are said to be of a very high quality. Check out the foil badge on the headstock. There's the lyre again.
As with the Revere drums and Stra-Do-Lin mandolins Sorkin later sourced cheaper, lesser quality imported ukuleles and sold them using the trade name recognition that it had built. By the 1970s, the guitars were from Korea, drums from Japan, and who knows where the banjos and mandolins were from. The badging of Revere instruments seems to have ended in the 1960's.
And then I came across a good picture of a Dick Stabile saxophone stenciled by Martin Band Instruments for Sorkin Music from the mid 30s to the mid 40s. The Stabile model is said to be one of those horns where the stencil is better than the manufacturer's "run of the mill," and Martin tenors from the mid 30s and 40s are no slouch. Here is a picture of the tenor on the left and an alto on the right.
Notice anything interesting about the logo below the name Dick Stabile and above the name Sorkin New York? Yeah, it's not a Stabile lyre, a Revere lyre, or a Premier lyre, the logo could really be called a Sorkin lyre.
Best I can tell, the Revere trademark was first filed in 1947 by the Peter Sorkin Music Company and is still held by Entertainment Music Marketing Co. of New York. http://www.company-records.com/trademark/REVERE-73387199/1347735 The trademark is held in common with the Multivox Corporation of America. Hey, we know them. These two entities also still hold the trademark for Premier amplifiers and guitars. Oddly, they also hold the U.S. trademark for Kohlert musical instruments (a well respected German company that stenciled different types of woodwind and brass instruments for Sorkin Music with the Revere name, including one of my saxophones from 1957, before going out of business in the 1960s).
If you check Ebay, you can buy a new Vietnamese-made Kohlert saxophone for about $700, which means that Entertainment Music Marketing Co. of New York and Multivox Corporation of America are still in the horn business and are presently using their Kohlert trade name. There are also new "made in the USA" plastic saxophone mouthpieces. It looks like Sorkin Music was the foreign wholesaler who contracted with Kohlert and ended up owning the Kohlert name.
My Revere badged Beaugnier tenor saxophone is the same horn as the Beaugnier "Perfect" model, another very nice horn. Mr. Saltzman was doing a good job finding quality manufacturers for the Sorkin house brands. These Kohlert and Beaugnier produced saxophones, even if in great condition, now sell for half or less than a beater Kohlert if they are badged Revere. So the name engraved on the horn can drive prices up or down completely unrelated to quality or condition. It’s that old trade name magic.
(addendum: I later found a 1958 Sorkin Music catalog and it shows the Kohlert Revere alto and the Beaugnier Revere tenor.)
