Looks like a Boyle Dayton, check if it has a light bar up top, most don't. Itlooks like an air operated, if it is don't be alarmed if you don't see a handle hole in the skins. Is the glass oK?
iirc, there is no light bar and i don't recall there being a hole for handle in the skins. the glass is great as are the number / indicator tabs in the glass / tank area. afaik, i have all of the original major parts, though don't have a hose or nozzle.
i hope to move it into the garage over the next few months, remove the non-structural parts, have it powder coated, reassemble and install in my garage.
at this point, i've got the talking part done so we'll see how it goes
