Aye, Don. The clocks all are similar on "Nifty", "Dollar", "Star", etc, but not the same. I'll mess with it a bit when I have a little time to spare: time is at a premium at the moment. This was so obviously marked it was an easy spot, and I've found the "Dollar" decoder online, as you noted it's still printed as "S S Adams $100 deck" but made in China as opposed to the ones formerly made by USPCC. That one's pretty straight-forward, as the 'clocks' indicate spades in the top center, diamonds left second row, hearts right center row (2nd down) and club in the 3rd row center. As far as reading the next card, how many left in the deck, etc - that all depends on you having the proper stack, and I'm pretty certain it's the same for all the DeLand decks. I believe someone already pointed out Theodore DeLand actually made the plates himself for these, and since they are single-color, it's an easy (??) but maybe slightly time-dependent trick to work it out - but of course being able to flip the cards around and see what you're looking at should make it almost trivial, I suspect. I've seen that $100 Deck (still branded as S S Adams) for sale for under $6 on Amazon in red or blue, and it's a stripper deck, so I wouldn't be surprised to find this one is tapered although it does not appear to be. Of course, it could be a very subtle taper. I found a 4-page PDF scan of the original instruction (I'm told the modern decks printed in China don't get into the stripper much) are quite complete for the currently still available deck, but if you look at the backs back in the OP, it's not a large clock face like that one, it's more of a circle with pointers inside type marking. I'm sure I'll figure it out and when I do I'll put together a PDF file using Acrobat to detail the "DeLand Nifty" decoder ring.
