[ Ref. 170115 MMD, "Unique Stoddard Ampico with Welte Pump" ]

I have a customer with a J. C. French upright piano with a Recordo
system in it, and inside the piano is a patent plate with "Welte" on
it.  I'm supposing the stack may be made by them, I don't think the
pump is, but now I will give it a closer look next time I service it.
