Here is a 1 1/2" Diameter Kinsley Steam Whistle Without Valve. The bell measures 1 1/2" wide, and 4" tall. Overall height is 7 1/8" and it has a 1/4" connecting inlet.
It reads Kinsley MFG Co. Bridgeport Conn. USA on the rim of the bowl.
It is in excellent overall condition with no dents or wrench marks.
I did take this whistle apart to lightly clean it inside and out, but I didn't remove the set screw inside of the bowl. (See last 2 pictures). Sometimes they are hard to get lined back up once you remove it.
This whistle works well with just lung power, so I wouldn't take much on air pressure.

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.

Be sure to supersize pictures for better details.

Thanks for looking.
