I don't know what CR stands for in this context. As a guess I am inclined to think it might be corrected but I could be wrong.
I think it was made in 2010, serial number is 10035.

CR just means that the Takahashi Mewlon-300 CR Corrector has been installed into an earlier model Mewlon. In this case this scope appears to be a Mewlon 250S with 300 CR Corrector.
The newer CRS has this Corrector factory installed along with cooling fans and a new style electric secondary focuser.
