Sheraton tune-o-matic bridge - is this missing parts?

Forgive my ignorance, I'm really mostly an acoustic player who dabbles, increasingly, with electrics. Still trying to figure out all the details with the recent AI USA Sheraton buy. The bridge differs from that on my Casino. The Casino has two thumbscrews, one supporting the bridge, one against the top, like so:

Whereas the Sheraton bridge has only one set of thumbscrews, supporting the bridge:

Is this just a different version/variety, or is something missing here? Is the bridge OK without extra support against the body? Maybe that center block is all the support the threads need? Thanks-

You're not missing anything. The extra set of thumbscrews seems to be a Casino / ES-330 thing, maybe due to it being hollow. They might help reduce tension on the top.

 

Here's a photo of a Gibson ES-335:

Another thing to consider is look how high the bridge sits on the Casino as compared to the Sherry. A second set of thumbwheels might prohibit the bridge from getting low enough for optimum action.

Relax. You are not missing anything. The ABR-1 bridge is designed to be used with only two thumbwheels when the posts are drilled into something solid. Your Sheraton has a solid block, so the posts have plenty of purchase and the top won't flex over time from any pressure exerted on the bridge by the pressure of the strings.

 

The second set of thumbwheels is typically used on hollow body guitars, like the Casino, as the top is thin.

 

A lot of players also elect to this when they have a leaning bridge, or as a preventative measure. Even is solid body guitar, the posts may lean from the constant string pressure over time, especially when the player sets the bridge high.
