Cream paint on a piece of wire.

With some pillarbox red.

Cleaned up and assembled into the frame.

And on the car. That makes me happier. It's not perfect but it's a lot better.

Were these ever illuminated like Wolseley grille badges, or  was it just exuberant Virgil Exner 1950s 'Wooo! Plastic's neat! Plastic's the future' kind of thing?

Very much "look what we can do with poly methyl methacrylate!", a really nice way of getting the dash with 3D lettering that's a lot more accurate than glass and cheaper than etching.

The whole car uses acrylic wherever possible- dash, the chief up front, tail lights. Only places not where I would expect it are the front turn signal lenses.

Cleaned my grease gun out and filled it up with new grease. Started greasing the points that I've cleaned up. Refitted the spring to the brake pedal, greased and oiled as applicable.

Cleaned all the old crap out of the steering box. It's worn to hell but it'll have to do for now.

Refilled with new grease. Looks like green ketchup.

And presto. In two days I have brakes and steering!

Today, I drained the gearbox of fluid.

I then undid the (37) bolts that hold it all together. I attached it to the crane (lifting point in the top of the case very handy) and pulled it up out of the way.

Hot damn is it ever heavy. Probably 300-350 lbs. I can't lift it!  On the floor it stays, unfortunately.

Sadly no. The "Hydramatic" name persisted all the way through to the early seventies, whereby it was replaced with just model numbers.

The one in mine is essentially the mk1.5 - ran from about '49 thru '55, with design revisions along the way. They have mine, which is selectable to gear ranges 1-2 or 1-2-3-4 and R. No kick-down, only a drop by oil pressure reduction to 3rd range below 65MPH with heavy throttle.

 They then changed the guts a little and made it the "dual-range", so ranges 1, 2-3-4 or 1-2-3-4 and R. It also included a "real" kick-down function.

Then the "turbo hydramatic", which introduced a torque converter and better control hydraulics. 

Then the name went onto the Jetaway which was the precursor to the modern TH-350, all very very different in design.

Found a decently-priced 1951 Pontiac Hydra-Matic Shop Manual for the gearbox on eBay and snaffled it up.

That should be in early next week, according to the shipping calculator. I think I'm going to pop the side pan off and eyeball inside. I really wish my waste-of-space ex brother in law hadn't ruined my air compressor.

Cracking quality bench that.  

Looking forward to the gearbox fettling. Autoboxes are made from voodoo as far as I’m concerned. #LearningOpportunity.

Huh?  This is pretty cryptic even for hairnet.
