Hey, I have the opportunity to check out a 58 jazzmaster body and warmoth neck this weekend.. Anyone know what I should look for to see if its as old as advertised?

The body does have sheilding in it, is there a way to tell if its vintage original or not?
And does anyone know if the 58 has the tack holes?

Any help would be appreciated.
