James,
the real deal as you put it, varies from car to car. Not all had the top nozzle.
Can you enlighten me as to what you think is special about the base plate, because as far as I can determine, the baseplates were standard, not custom pieces (well they look that way from the outside anyway).
Cheers,
John.

Correct, the top nozzles varied on some cars - but most had top nozzles.
My variations were also done during the manufacture of the coolers and not bodged up retrofits likely to cause debris in the matrix. The coolers were also anodised, inspected, tested and certified for Airworthiness.
The base-plates I have were opened up and the central bulkhead removed.
The larger Variotherm nozzle was used for connection instead of the side nozzle and the internal runs from the Variotherms to the side nozzles were also removed to improve bottom flow. Permanent plugs were also inserted.
I hope this clarifies.

John,
There are also two types of cooler in this size and flange fixing.
The other one has the wee-wee hole from the top tank down the centre of the core to the base and the base plates for these are also different internally.
I went for this design to get full flow through the surface area of the two sides of the cooler simultaneously - top to bottom with minimum dwell as it were.

Here is another one, but not claimed as a Holman-Moody piece, that seller says came off of an airplane or helicopter:
I would be very cautious of using any used oil cooler (as mentioned on some old threads) without sending it out (read costly) for refurbishment. Unless against the wall for an original, I would polk around I think one of the older threads has places that have simlar new ones that could be made to look close to original and reworked as needed. Not worth blowing a motor due to unknown particles in a cooler of unknown origins IMO. But it is a definite cool looking part, not so much that I wouldn't spend a good amount of time/$$ to start with a new unit.
And yes, Lynn definitly finds some damn cool stuff on ebay.

That is not a Continental oil cooler. The base is a bastardisation.
The Continental aircraft cooler also has a "wee-wee" hole which I am not too sure about for our use. This duct mitigates freezing or sluggish oil at low temperatures which is not a problem in any GT40s.
Sandy is spot on the dollar with his reminder regarding debris and I have three other coolers which have been ultrasonically bathed to clean but still I am hesitant to use on an original GT40 engine. Aircraft engine tolerances are built to a strict schedule of regular overhauls. Road car engines are not unless you are kidding yourself.
As Sndy also states, these things looks cool, the but you must weigh the risk of mechanical lubrication failure against a cheap nice to have.
If you use them in a MkI your layout also needs consideration.
I use old guns all the time but always buy new cartridges.
