is this a model M?

Here's an odd looking birth certificate...

What is "Product of CCC"?

Is there some other company that makes model-M-alikes? (And can they make me a mini?)

That's an original model M (double-key caps, IBM logo, high keys for buckling springs etc).

I think that certificate isn't the original one... rather, some generic sticker stuck on by the leasing company. I could be wrong, but that's what it seems to be.

It's probably just a label overlay or replacement label for a company who owned it or resold it.  The label is actually wrong.  The IBM model number it says it is is 42H0468.  But that's not a part number for a Model M, it's a part number for a model M2 (see http://sandy55.fc2web.com/keyboard/42h0468.html), which looks a lot different.  I'd ask the guy to clarify or steer clear.

The master says -

I'm not sure but it's told that the keyboard is essentially for IBM terminal 3153.  But it can be used with usual PS/2s or AT compatible computers

It has the same sort of keycaps as that M2, so perhaps it was a replacement for when the M2 went out of production.

That must be it.

But that raises the question: WHERE'S THE BIRTH CERTIFICATE  (Tee hee hee...)
