What is this cast iron pan used for?

I've seen some similar pans, but not quite the same. What is its purpose? It's pretty small, and the bottom is flattened but the insides of each hole (for lack of a better word) are rounded.
No marks. Thanks for your time.

 

With the diameter of the depressions,it looks like a takoyaki pan.

 

Thank you Davey & Hollyblue, I'm searching your suggestions now. It does seem though that the cups are very small to make muffins? Much smaller than my normal muffin pans.
Thanks!

 

It does seem to fit the proportions of a Takoyaki pan, but I don't see any pans that look like this one, most seem to have a handle on them, and mine appears older than the others I'm seeing. Is takoyaki a newer thing?, or have they been around a while?
Thanks again

 

Oh and that picture looks really good and just made me hungry.... thanks a lot Davey. Now I must go to the kitchen and be a piggy.

There are some similar little items called "gem pans" or "golfball pans" that were 1800s and small like yours... I'm looking for a better example, but...

This pan would be called a golf ball gem pan without cut-outs. Originally "Gem pans" were cut-out pans that allowed for even circulation around the small cups. They were first patented in 1859 by Waterman. "Gem pans" were/are muffin pans, but for small muffins, and in reverse not all muffin pans are gem pans. Seems no one knows how the name came about like whether there was a company name Gem who made them or because these pans made small round muffins resembling gems. Since the first gem pans with cut-outs around the cups, other configurations were made such as this one without cut-outs. The cup shapes range from round (golf ball), hexagonal, cylinder to elliptical, shell, "turk's head's," .... Following is a link with the history of "gem" pans. The bottom half of the page has a listing of gem pans made by different companys. Most of the pan listings are hyperlinked to a pic.
