The Tall-case Red Welte pianos were the first upright Welte pianos with
keyboard.  The earlier cabinet version had had no keyboard.  I think
all were built into a Steinway Vertegrand piano.  This series started
in 1907, Steinway serial numbers from about 127xxx.

You can find pictures of a restoration of a Tall-case Red Welte at:

This seems to be a 1908 version.  A later 1909 or 1910 version is shown
at: http://www.britannica.com/EBchecked/topic-art/464394/6950/Steinway-Welte-player-piano-1910-in-the-British-Piano 
This series was discontinued about 1910.

I own two of these Tall-case Red Welte pianos and bought both in Great
Britain.  These Steinway Welte pianos also have been imported to the
U.S.  The  book "Automatische Musikinstrumente aus Freiburg in die Welt
- 100 Jahre Welte-Mignon" shows on p. 168 a picture of the Welte repair
shop, certainly in Brooklyn, with a Tall-case Red Welte in the
background.
