The engine is clearly a Ford.... I have the same on my boat, but marinised by Thorneycroft...... on mine the exhaust manifold is totally different (its square) and has a Thorneycroft badge on it.
Can't help with the box though...... mine has Velvet Drives...

Apparently Ford 6s were matched up to PRM gearboxes but I can't find any pictures that match (it's hard to tell from that photo though)

When you say
"It is in workboat attacted to a Ford 6 cylinder diesel my club is selling on ebay"
Can you be a bit more specific? Is it the engine 6.6L engine? Maybe you know the model No.? If it came out of a work-boat it would be quite big?
Clive
NOTE
Looking at it again I think it is a Fordson Major engine circa 1955.

Your's might be a Ford Lehman because Thornycroft did the marinising for them

I haven't given up!
You reckon that's massive! While researching I came across this (they knew how to make motors in those days!)
Fairbanks Morse Diesel Engine. 1940’s vintage. 4 cylinder 120 Horsepower @ 450 RPM. Direct reversing. Weight: 8 ton. All brass gauges and a nice large Brown and Roots Pyrometer also engine manual. Engine is setting on I beam engine stand. Removed from small tugboat that never saw salt water and was keel cooled.
I enjoy listening to my favorite music on the Internet while I work out a problem like this as they say it delays the onset of Alzheimer's. Maybe my Alzheimer's is well advanced though because I couldn't count the "F"s in this link correctly.

I think we'll find the gear-box is an early PRM.

I don't think I am going to be much help. The nearest I can get is a gear box made by Self Changing Gears Limited Coventry.
Your gearbox is along the same style design-wise but it is not the same.

Maybe this could help?
If you look at page 2 and 3 is lists all the gear boxes that R & D make parts for and
It gives a whole lot of dimensions for each gearbox as well.
Could you use this information to identify the gearbox?
