hang in there..there are board members more knowledgable than myself on Hamers, but I own a USA Cali..serial number is a good place to start-need to see if it is a USA or a Korean model
if its real cheap, than prob. a Korean model
Most Californian Deluxes should have a mahogany body, maple neck with a ebony fretboard, with dots and two boomerang inlays. Made in USA. Kick *** guitars.
