That's a nice one Nick!  I don't recall seeing any etchings that look like yours, I suspect it was made by Union Toy Mfg in the late 1870's but I'm not sure.

Here's an ad from 1873 showing the cylinder mounted on top of the boiler.  Note that it came in two different sizes and two different configurations, plain and ornamented. 

I find it interesting that it's supposed to shoot water 20 feet.
