Here's another offering which gives a bit of an idea what life in the pit lane was like in those days:
Far too many people, many of whom were not "savvy" as to the dangers and often got in your way. When you work the pit lane you develop a sort of sixth sense as to where the cars are and where they're coming at you from. You also know where to be when a car is coming at you so that you can take tyre temps or whatever you needed to do without hindering the team mechanics. In those days the "hangers on" would often get in the way and it was really very dangerous. Surprising really that more people were not seriously injured?
Matra ran Good Years I seem to remember, don't think Michelin (their obvious choice) were much into racing at that time. I never actually got to work on one. Adequate compensation came from the privilege of just sometimes helping with a works Ferrari. Ferrari were our "big name" team in endurance and F1. I should explain I was employed to service the European Touring Cars but for big sports car races, especially those of 12 and 24 hour duration, there were never enough permanent staff so we (being enclosed wheel arch people, unlike the prima donna Formula guys with their accessible open wheels - much more difficult to push a pyrocon (thermocouple) needle into the tyre on a vehicle with enclosing fenders - would be seconded to help, as long as we ourselves were not racing that weekend.
The 512M was one of the fastest and won many races. It had a most unique engine sound, much more gutteral, not like the Matra screamer although both were V12s:
The tread pattern on those rears look like our intermediate R125's but usually there would be big white Firestone lettering on the side. We were a smaller and less well funded set up compared to Good Year and it was always important to us to get our Firestone
stickers on any of the cars running our tyres. I've had a few dodgy moments trying to secure
stickers on cars as they were about to exit the pit lane!
Oh my, how I loved that job! Probably a good thing that Firestone shut down the European racing division before I became totally besotted. Most of the engineers in the department were either single or divorced! We were all passionately married to the job, you had to be, the hours you worked were insane, especially on the 24 hour endurance races, often 3 days on the trot sleeping in the back of the pits or one of the wagons. Absolutely loved it and wanted more!
Ps. just noticed they are Dunlops! Their inter pattern was very similar. If I'd noticed the mold flash down the centre of the tread and slight displacement of the blocks due to the 2 mold halves not being aligned I'd have picked up on that! our tyres were mostly hand cut so the patterns were symmetrical and even over the whole width of the tyre.
