I spent most of yesterday afternoon separating parts (75%) from trash (25%), & it turns out there were TWO of these distributors in the parts pile afterwards. Both are early 850 Marelli, one is an S118BA model, the other is an S118BB model. They were both really grungy, but a little cleaning has made them more presentable:

The S118BA is mostly complete; it needs an ignition condenser (the retaining screw is still in place), & it's missing the small bolt/washer/nut that holds the black plastic wiring connection insulator onto the upper edge of the distributor body (the points & condenser wires connect to this). A previous owner has fitted a custom alloy oil slinger/bushing onto the main shaft just below the distributor body. The main shaft is a little stiff when trying to rotate it, likely due to a P.O. using a heavy grease between the shaft & body. This stuff was old black goo that has hardened with age - I cleaned a
lot of it off of the upper shaft points-contact lobes, & it rotates a little more freely now.

Thanks for going through your parts. Would you consider selling either one. My first interest is in the S118BB model. Thanks Again. My 61 600 is near completion, and I would like to close the engine lid.
The S118BB is complete, but someone has installed the original black plastic oil slinger/bushing upside down on the main shaft. The 850 Spider side-entry style Marelli distributor cap is "like new" on the inside with no noticeable wear on the 4 brass contacts or the center carbon brush.
