If the model has a stiff tail drive shaft (doesn't wind easily holding the head and tail) and push pull controls then it's a Custom 60.
If the side frames are one peice and cranked it's 7-14 years old!
Plastc radio tray and H radio tray brace makes it one of the newer Customs.

You can still get parts as usual with MA, but some will be the latest versions that still fit.
