I'm not 100% familiar with the ES60, just the Japanese ones - but to me at least it looks legit. Rich? Oze? Anything here that looks dodgy?
As for machine heads - I don't know any perfect drop-in replacements, but they're made by Gotoh (sadly not up to Gotoh's usual standards it seems!), so start there; if you don't want tulip heads, you may be left with the top holes open, but I've seen people replace them on their love rocks and the bottom screw is a perfect fit. A good general rule of thumb is to try to get some from a local shop on approval to make sure they fit.
And finally, remember to string that bad boy with 10s at least to get the best out of the scale length!
