Photos of our very poor condition build sheets (recovered from above the gas tank). I believe someone reproduces build sheets, however my specific question is are my original satisfactorily for judging purposes?

Re: 72 LT1 original build sheet question

They are not ever used in the judging process.

So, place it in an archival plastic sleeve, and store it in your files.

Re: 72 LT1 original build sheet question

Patrick, thanks for the information. The build sheets a in poor condition (but the options can be read), I have them in archival plastic sleeves now.

I suppose the're historical data information for our specific 72.

To truly preserve, do an electronic scan of the document. It will capture codes and coloration. Expect that over time it may deterioriate further...this way the electronic scan can be used to zoom and see codes.

will do, thanks for your advise

If storing electronic media long term one needs to be sensitive to changes in technology. There used to be 6-inch floppy disks (that were truly floppy which is where the name came from -- I think there were 12-inch disks even earlier, but I will have to defer to others for that history) and 3-1/2-inch disks and CDs all of which are difficult to extract data from. They are becoming more difficult as time goes on. And I am vaguely aware of storage media even earlier than the 6-inch disks, but my point is that one can lose data from the advances in technology without being aware of it. Store it and forget it is not a good idea.

Hi Terry,

I'm of that age where I have one of those oldest original "floppy", although I don't have a reader for it any longer. They were 8" and used in industrial computer settings to boot load the mainframes starting around 1971 and replaced the paper or mylar load tapes. They were eventually superseded circa 1980 with the smaller 5 1/4" floppy used in the popular IBM PC. The 3.5" disk was actually developed by Sony in the early 80's but didn't gain popularity until the mid 80s.

Sorry to get off topic in this thread, but I love talking electronics ...

Terry,

Yes! 12 inch floppy on a Xerox word processing machine. Beautiful screen - very much like looking a IBM Selectric typed page.

In addition to that electron storage stuff, you can have a quality scan printed out on photographic paper. No matter how technology changes, likely to always be able to create an image from a paper document.

Thanks to Dave & Bill for the history lessons. I knew there was some earlier storage systems, but not the details. Sometime face to face we will have to talk about the airborne program storage I worked on in the early 1960s, but that would take the thread way too much off topic for now.

If possible print on low-acid archival paper. Store in archival safe plastic sleeves. Google "archival materials" for sources. They are not inexpensive, but worth the cost. One might want to investigate the longevity of different types of printing. I suspect ink jet printing might stick to the plastic sleeve, but that is something to investigate.

Fred,

Bags unlimited is a good source for acid free archival plastic sleeves https://www.bagsunlimited.com/xsearch

Also, you can get acid free supplies from a Comic Book store, if you want a small quantity.

Re: 72 LT1 original build sheet question

Hi Dave, thanks for the advise. We will get the sheets scanned, the're very fragile at this point.

Re: 72 LT1 original build sheet question

Archival document preservation is available through many rare book stores or at a local museum. They work on much more valuable documents and the charge is normally quite reasonable. They can nuetralize the document and stabilize it or even reconstruct a doc.
Scanning such a fragile document could cause more damage- Get someone with a high quality camera and GOOD LENS to set up and take full rez images of it then blow up and print.
You can use photo shop to invert the colors etc to bring out what ever is difficult to make out. I pushed the saturation levels and then the contrast to really bring the text out on my tank sheet.
