Cow creamer.

I got this creamer in a box of stuff at an auction. The bottom says "WHIRLEY INDUSTRIES, INC. WARREN, PA., U.S.A." in a circle on the bottom. It also has a raised 3 in the center of the bottom. I tried finding it online, and I have been able to find several other creamers by this company, but not this exact one. Infact, there were quite a lot of creamers by this company. I was able to find one small picture in a image google search, with no information on it. I'm just wondering if this is a rare one since I can not find it in anyones collections. Can you help me out here?
