IBM 1620 Card Decks

While picking up most of the Burroughs manuals I posted about earlier, I had mentioned to the woman that I was also looking for punched cards. Today she found some "IBM" cards with "Leo Computers, LTD" on them! I have probably about 30 of them now and they will make another neat addition to the collection! Again, I picked up most of the Burroughs manuals including the ones marked "Company Confidential". She talked with a friend of hers who worked there who said it was okay to take them. Apparently they were marked that way only for competitive reasons and those reasons no longer apply :)! Her friend who wanted to look at the IBM stuff will be here Thursday and she will let me know then about the stuff. Most likely it will all be available. When I get it, I'll post a list of what is there and it will be available for the cost of shipping.
