I have found this in an auction, but i don't know what it is and it is possible it is not aircraft related.
If not please let me know and i will do the necessary.
It seems to have a bellow missing, anyway i am trying to find out what it is, if you have seen one before please let me know and i would be much appreciated.
There is a label on the right which says:
A.S. & ALT. SERVO
TYPE HB-1
AC- 1594169 SER. 14971
THE FULTON SYLPHON CO.
I have never seen anything like this so it would nice to be able to put a name to it and maybe learn something about it.
If you need any more information please let me know
Thanks
