U.S. Machine Cancel Identifier – Pneumatic Machine
![[pneumatic machine cancel]](../machines/pneumatic_example2.jpg)
Your machine cancel was made by a machine sold by the Pneumatic Cancelling Machine Company of Indianapolis, Indiana. The impressions from these machines are quite distinct from other machines of the time. They are somewhat common from Indianapolis, but less so from the few other cities where they were used.
There is a bit more information available about these machines on my Machine Web page.
