IM did loan me the 1600 super script badge. I've been through all the fonts people have shared and also scoured the Internet. I'm afraid I can find things close enough for individual letters but none of the fonts are correct.
It appears the 1600 is likely one font, and was slightly modified by Porsche and the Super script is definitely a different font and I can't find it but have found some similar letters.
At this point I think I'll need to sit here with the calipers and do take-offs of the letters I need and then find something similar for the 2 and 5 characters that suits the number font and try and make those. It's a bit of a slow process...
I must say I am really shocked no one has recreated the typefaces. I did use What The Font? (handy resource for identifying typefaces: https://www.myfonts.com/WhatTheFont/ ) to help find some similar ones, but like I said, not all letters match. That isn't uncommon, I recall a designer doing a logo for us and tweaking the fonts a bit to make it unique. I think most corporate identity folks do that, I'm just surprised that by now no one has done a reasonable recreation of it... If you do have one lurking somewhere, or even a JPG or GIF of more text in either of the two fonts, please share it.
If I get it drawn up and am happy with it I'll share my badge when it is done.
Thanks,

PS: The widely available "Porsche/Porsha/etc" font looks like a better match from the early 911 until probably the late 90s. If you look closely at the shape of the P in Super you'll notice it is different on the 356 badge. The font for Super is very much a 50's feel and a bit narrower and "chubbier" in the letter detail widths. It's actually a really neat font the more I look at it, I wish I could find it...
