Here is a 3" Diameter Steam Whistle Without Valve.
The bell measures 3" wide, and 5 1/4" tall. Overall height is 11", and has a 1" connecting inlet.
I'm not sure what maker this whistle is, but the acorn (finial) on top looks like Penberthy.
It is in very good overall condition with no dents in the bell.
I did take this whistle apart to lightly clean it inside and out.
It has a nice patina, and is ready to work with a 1" valve.
Nice display piece also.
Please check out my other auctions on now and in the next few weeks for more steam related items. I do combine shipping and pack well.
