I need help to identify a small 41 key piano (Herrburger Brooks Ltd action)

[paulmk5]

Hi, I'm new to this forum & pianos but I'm looking for any info on a piano that I've come across. I don't want to keep or restore it but I'd like to know more about it like age etc. so I can sell it.
I've looked all over the web but can't find anything about it or anything similar.
It has the stencilled name Steinburger and the action has the Herrburger Brooks stamp plus there is a serial number - 25058 stamped above the strings. There are no other names or numbers that I can find.
My thinking is that it could be an apprentice piece rather than a child's piano because the keys are full size and it all appears to be hand made.
The pedals aren't connected to anything and the action is a bit less complicated than normal actions I've seen as there are no dampers or provision for dampers above or below the hammers.
The approximate dimensions are - (W) 29"(74cm) x (H) 33"(84cm)
Thanks in advance for any help.

Hmm.  I'm curious about this instrument too.  Can you provide some measurements?  Like.. floor to keyboard, key length, key width, total width and total height? 

I've heard of "Tom Thumb" pianos before... sort of mini versions of standard uprights, but they're generally functioning instruments, whereas this one seems not to be.  There are several things that seem "weird" about it... like the very short compass (41 keys is extremely short), and the stringing itself (which, among other odd things - seems to be the same size and material string, double-strung top to bottom if I'm seeing it right?).
 
The apparent manufacturer of whatever action you have sounds like this one: https://www.piano-tuners.org/herrburgerbrooks/ but it seems quite odd that they might put their stamp on something non-functioning, without dampers, etc.
 
What happens when you depress a key?  Does a hammer move to strike the strings?  Is there a damping action that is happening that might not be obvious when you just look at it? Does it look like the pedals COULD be hooked up to something (i.e., are there parts there?) but just aren't?

Hmmmm.... Tell us more.

Hi, thanks for the reply.

Measurements are -
floor to keyboard (top of key) - 17 1/2"
key length (full length) - 11 3/4"
key length (white plastic part) - 6"
key width - 7/8"
total width (across the top) - 29 1/4"
total height (without castors) - 32 1/2"

This is sort of a functioning instrument in that you press a key and the hammer strikes the strings and returns as a standard hammer would do and if you keep your finger on the key, the hammer falls back about 1/4". There some standard action parts like bridle tapes and regulating screws and buttons for adjusting the jacks as a normal piano would have but I've looked all over and there is no dampers, damper rails or any kind of damping occurring anywhere.
The strings are double strung from top to bottom and the top 14 strings are all one size and thinner than the rest of them which are also one size (none are wound and all are of the same material).
It does look like the pedals could and should be hooked up to something but they aren't. It doesn't look like they were ever functioning as I can't find anything that they might have attached to.
 I've already checked out Herrburger Brooks but haven't been able to get any info other than a brief history of the company and although they were the oldest piano action company in the world, I can't find any way to even date it let alone identify it fully.
Maybe this was an apprentice piece which never quite got finished - this may be one of those questions that never gets answered.
Thanks again
Paul

I would try posting over on the other forum (pianoworld.com) in the tuner/technician group.
