Stuka engine installation

 The engine is a Junkers Jumo 211 inverted V12 putting out 1000-1400 hp depending on the model.

Sidecar Sunday

 The Hawker motorcycle racing team at Brooklands circuit. AI tells me  that's Leslie “Red” Parkhurst with the passenger named for once,  Fred Ludlow.

Used and abused...

 Here's an old "multitool", a combination monkey wrench and hammer. Looks like the outer jaw is adjusted by rotating the handle. No manufacturer's name that I could find but it looks like it has seen a lot of use.

 

Driving test

  With the blast furnaces in Gary, Indiana in the background,  this ore carrying laker is making use of the turning basin, no helpful tugs present. I think this might be a defining moment for any aspiring captain. 

Vacuum power brakes

 And there you have it. Modern power brakes, pretty much all there by 1936. Some car manufacturers were still deciding whether brakes were really required on all four wheels...

One of my vices is vises, Rockford

That is a large heavy 4 inch vise. Once again, very little history on the company that I can find. 

 

1930s Wyandotte pressed steel Streamlined Speedster (updated)

Gorgeous! Another toy I would have appreciated less as a kid.

 Update; Claus sends these images of his car/trailer combination. I agree with MARSHALL in the comments, this needs to be a full scale replica.

MGB GT

Probably 1973. In factory correct Harvest Gold, looks like sandy brown to me. 

 

Update; Derek sends some images of the original harvest gold touch up paint from Unipart, the spare parts organization of British Leyland.

Know your roller bearings

I'd suggest that the cage should have been illustrated as a separate part. I do approve of the handlettering...

Big casting

Robert Gordon, Patrick Mahone, The Texture of Industry, Oxford Press 1994

  In this photo foundry workers pose with a mine hoist sheave wheel they have just cast in a sand mold. The wheel would have been cast flat and has been stood up with the wooden jib crane on the left. It tuns out the foundry is the Knight foundry in Sutter Creek, California which amazingly is still operating, the last water-powered foundry and machine shop in America.
