New (to me) '52 Ford F1 w/V8 flathead and "Saginaw" 4-speed

Hello:
I'm finally in a place I could buy a project, and I have. A '52 Ford F1 with a flathead V8 with Offenhauser heads and intake. It is a "mid-project" redo by another person. I was told it was an "older" V8 but he did not know what year. It was available, he bought it. I''ve followed the other threads to identify the motor but have some confusion. It has 24 "bolt" heads(?) With Offenhauser heads can you replace the studs with bolts to use the Offenhauser heads? It does NOT pass the pencil test. The pencil has no room on the block to rest.

-It has a cast bellhousing.
-It has a "59" cast into the top of the bellhousing area plus some additional characters above it - still trying to decipher what they are and how to post pics here.
-The intake is not "raised" from what I can tell. It is flat.
-Water pumps are in the block.
-Fails the "pencil test".

I'm leaning to the 1945-48 59 series with 239 c.i. but without dismantling parts off the engine to see water passages and holes, and bore size, I'm not sure how to narrow it down.
Where are the core plugs in the oil pan rails?
Suggestions?

I was told by seller the trans is "Saginaw" 4-speed. ??
Every search I've done online comes up with GM products from the '70s. A few point to the Chevy Vega! Is there a Ford "Saginaw" transmission? It has a fresh, new looking shifting mechanism on it but obviously meant for a car with a short shift lever. Seller welded an extension on shift lever and it has a LONG throw on it to shift gears. Main reason to identify trans so I can get a new shifter mechanism better suited for an F1.
I have pics of the sides with castings but am new to posting. Pics to follow.
Suggestions on approach to identify this transmission?

And, I'm missing a cover for the bottom of the bellhousing to protect the flywheel/clutch area.

yes, 59 series, probably 239 displacement. Some of the large trucks running these engines had that style oilpan with removable lower section, in order to be able to replace the big 11" clutch without the neccessity of removing the oil pan. Those 59 engines don't have the freeze plugs in the pan rail....
 
As a follow-up: I got around to making a list cover for the clutch-flywheel to mate the Speedway Motors adapter bellhousing with the GM Saginaw trans. I made a wooden form to fit. Then I made the cover out of metal to mate. Not show quality, but it works.

Open clutch/flywheel/pressure plate.

Wooden form I made and the sheet metal cover to fit. Tack welded together.

Brazed everything up and painted.

Bolted in place.

Very good job of making that cover from scratch! Not all of us are shooting for 'show quality'. Many choose to go the extra mile to either satisfy the judges in originality, or with custom parts they might grind, fill, plate a custom part until it blinds you in the sun. More power to both of them and I enjy their threads. But personally, I have lots of room for a guy without a lot of tools or a professional garage to work in, who just makes parts for his truck because he needs them and enjoys the journey. More power to you. GB
