Wurlitzer, starting around 1900 until circa 1935 produced nickelodeon pianos, or coin pianos, which are electrically operated player pianos that take coins to operate, like a jukebox.

The company produced various models of nickelodeons, such as the early Wurlitzer Mandolin Quartette – Wurlitzer's alternative to the Regina Sublima Piano.
This machine has a reiterating piano with mandolin attachment along with an accompanying piano.
They later introduced the Wurlitzer A.P.P. roll; a universal roll to be used on all subsequent Wurlitzer nickelodeons.
Models such as the B(X), C(X), D(X) and I(X) use this roll.

Wurlitzer also produced an automatic roll changer system so when a roll finished rewinding another was put on in a carousel-like system.
An 'X' at the end of a model number indicates that model was fitted with a roll changer.

Records indicate Wurlitzer sold player piano mechanisms to other manufacturers who installed Wurlitzer components in their own pianos and sold them under other brand names.
One example is the Milner player piano company.
Milner pianos were built in Cincinnati at a time consistent with Wurlitzer's presence there.
Company records suggest Wurlitzer acquired the Milner company in addition to the several other companies acquired by Wurlitzer over the years, but it is possible that Milner may have simply used Wurlitzer components in their own product.
