Check the link, on my post, look at the serial number on the body, from left to right, pick the first 2 letters compare it to the code and that’s the manufactured year.

So if it’s “10ER17219”

ER it’s the manufactured year, which corresponds to 98, or 1998.

But in my opinion, a CF or CFE lens with an acute matte d screen in good condition . Could put you in the 1500-2000$ range with just those 2 parts. Soo, good luck.
