Vintage Bridgeport Milling Head Identification

[Maui]

I just picked up this Bridgeport milling head today. It looks smaller than either a J head or an M style head, and the serial number on it is H393. It did not come with any collets, so I need to figure out what will fit in it. Does anybody recognize this style head?

That appears to be a model C head. Apparently their first head.

So this head could actually date back to the mid to late 1930s before they even manufactured their very first full fledged milling machine?

Yes, the C head was designed to be mounted to horizontal mills to give them some vertical machining capability.

Morse #2 collet size was common on early B/port heads.
