They did make some instruments to be re-branded by Buegeleisen & Jacobson but one of the currently living Favillas told me that this was the only OEM work and with everything else, if it doesn't say Favilla, (or Marca Aquila) on it then its not, (though he told someone else that Favilla made some Baritones for K and K, and this was the only OEM work? And the Marca Aquila Winner?) Though famous now as a Ukulele maker only about 10% of their output was Ukuleles. a firm incorporated in 1921 so it can't just have been rebranding old stock! it is also the case I have seen quite a few Marca Aquila Ukuleles which pre 1910 would have been very early for a mainland Ukulele - though then never looked that early and nowhere outside of Favilla history are they mentioned? Mind you Favilla's Official line is they didn't do OEM - apart from all the times they did!!)What is for sure is in the 1920 Favilla was recorded as employing 55 staff so it was no longer just the brothers. From 1890 to 1910 the Instruments including Ukuleles were labeled Marca Aquila, then they were labeled Favilla Brothers until 1919 when they became Favilla, (This is the official line but I know its not completely true and I have seen a Favilla made Winner with the Marca Aquila soundhole label in it and the Winner name wasn't registered until 1924 by the Manhattan Band Instrument Co. The company made all sorts of chordophone including some violins, moved around New York, tinkered with the name, (in the end it was Favilla Guitars inc.) and finally ceased production in 1973. Brothers John (Giovanni) and Joseph opened their first music shop in the US in 1890, (the family had been making instruments in Italy prior to that), and in 1884 they started the musical instrument making company, initially as Favilla Bros.

Favilla & Sons were one of the major New York Ukulele makers.
