Cat 246 Skidsteer Year?

We just purchased this used Cat 246 skidsteer, just to be used for cleanup work & shuttling our paint wagon in & out of the paint shop & I wanted to ask if anyone has access to identifying the year of this unit from the ser #?

Also, the ser # tag seems to indicate it may be a "C" model, as a C follows the model number?

The ser # is CAT00246C5SZ07730. We bought this unit very reasonably priced in an "as is" condition.
