MG TD TF 1500 - Marshall 75 supercharger drawings

Back in the 1950 and early 1960s, when Canadiar (today Bombardier) was building the F84 and F86 for the Royal Canadian Air Force, the cabin pressurizers were being supplied by Godfrey Engineering in Montreal. These pressurizers use the Marshall T75 compressor, which was adapted as superchargers for many English cars including the TD.

When Godfrey closed their office, I was given two T75 installation drawings by Downes Engineering who had made a kit for the TD. I sold my supercharged TD many years ago but have had these drawings hanging around ever since. I would now like to give them a new and good home.

One is not of high quality, being rather dark, but nonetheless quite readable. If these drawings were scanned properly, I’m sure a good photo-editing program like Photoshop using the ‘similar’ feature can bring a quality drawing back to life.

They are D-size and will need to go on a drum scanner. So I will give them to the first person to ask, providing they HAVE ACCESS TO A DRUM SCANNER, and on the following condition:- That you will send me a copy of the un-retouched image files, or raw so that I can clean them up and make them available to others upon request.

I’m attaching a very poor reproduction of the poorer drawing. I took it in strong sunlight and wasn’t able to improve on the contrast. The other dwg is normal.

First person to agree to these conditions, gets them (to keep) and I’ll even pay to send them.

Gordon,
I can scan them and will return them.

You can also take them to a Staples Store and have them scanned.

I did this with a pattern for the windshield on my TD.

To bad images are so limited on this board, or you could post a copy of the full scan. A reduced image would still be nice, but all the original details would be nice to zoom in on.
I don't believe emails woul even transmit such a large file, but maybe they've evolved enough to?!
