This is an excellent site for identifying the Best of the makers. But, there are many fun threads throughout the year identifying "stencil" brand names. Off brands are usually easy to identify because they are variations of manufacturers standard models. Occasionally I come across an instrument design that is unique in so many ways as to be difficult to name the source. "Maxitone" banjo ukuleles were distributed by Bruno NY, but I can find no comparable banjo w/ such unique features : ( metal pot, no neck brace, gumby peg head & elongated flat neck up to the 2nd fret). Who made the lowly 'Maxitone" metal banjo ukulele ?
Lange made some nice banjo ukes for Bruno, & they have many Lange features & hardware. I'm wondering who could have been geared up to produce & deliver 3200 metal Maxitones to Bruno in 1927 ( see Lardy's Ukulele Database).
