Looks like the real deal. It's either a Rick 900 or an Electro ES-16. Looks very similar to my '64 ES-16, with the neck thru construction. The bottom horn is curved on the front edge whereas mine is straight. There were many variations on this body style. Groovy!
The bridge is the same as a 400-series guitar. I bought a replacement bridge assembly back in 1980. It came with a new compensated bridge and a chrome bridge support.
