Football club crest: what font is this?

The picture in the link is the crest of a brazilian football team. I searched for quite a while for letters like this and wasn't able to find anything.

To what genre does this belong? Does anyone knows fonts that look like this?

I have never been an active member of this site until now, but I've been visiting Typophile for more than a year and I can say this community is truly amazing!

Thanks in advance.

Internacional SC crest


The logo is pretty much a dog's dinner: the I might be qualified as a Gothic Tuscan, the C is similar to an old late-1800s ATF face named Concave, and the serifs on the S don't match those of either of the other letters (besides which, the two serifs don't even match each other)...

Thanks a lot for your input! Anybody else?
