Early Ford transmission

[[email protected]]

Hi guys

While I am waiting for my engine block that is still in the machine shop I have taken a closer look at the Transmission.
However I don't seem to find any information on the Internet that can help me identify what it is.
It looks like a fourspeed toploader. There are some reinforcements on the bellhousing that I have not seen on any other of the Transmissions.
Nothing at Van Pelts that can point me in the right direction.
