Help me identify this Strat

[bill1951]

I picked this up for $100.
The only number I can find is on the neck plate - 01778. According to info on the web, that refers to a 1956 date. But the headstock is large which is confusing.

The saddles are 3/8" wide each and 2.5" wide total.

I'm thinking maybe someone put some pieces together here?

Those look like ceramic magnet pickups to me, so I'm guessing it's a MIM strat, or at least they came from one.
