Nope- the model numbers are whatever Crosman decides to put on them. The platform has been used on 20-30 models Crosman has sold over the last 15-20 years, including the Quest, Phantom, Optimus, Classic 22 and others, then the standard 'NP' models (NOT NP2 or NP XL models, they are physically different). The rifle you have appears to be called an "F11"- which should have been on the box it came in if this is the case.
