OK, I went to another Radio Shack store that had them in stock. Here's what I found:
There are TWO models:
1) model #12-803. This is green and black, and is the radio texascarl and I link to for reviews. Receives weather, AM/FM and six SW bands. The Radio Shack website says that this model is discontinued...the clerk at the store that had some said that his computer gave no indication that this was the case. Currently "on sale" (what isn't

) for 49.95. I bought one. They call it "Self-Powered Portable Radio". Bears Radio Shack name--don't know who manufactured it. Clerk said Radio Shack made it...riiight
2) Dunno model #. Made by Grundig--appears to be the same grey radio that is sold by other vendors. I was immediately put off by this one, as the display model exhibited a printed staition indicator card that was printed on a very thin film that had delaminated from the substrate, rendering almost half of it utterly useless to indicate tuned frequency. (Didn't make a great impression of the store either!!!) Also, it has lesser capabilities, receiving AM/FM and SW1 and SW2. And I'm aware of no reviews of this product. Price 39.95.
So far, I like 12-803.
I've only played around with it inside the house so far, and have gotten stations from Japan, Sweden Germany, Australia tonight. Of course I also got some in languages I can't identify, Spanish, and a bunch of Bible-thumpers. The simple antenna in texascarl's link helps. I think I'll try to rig up one out side that I can hook up to.
It seems pretty sturdy considering how many things are made nowadays, and you can switch to AA battery power while you crank it back up. Dunno if I will get a wall-wart power supply for it or not. The knobs have a good feel, but I can see why serious shortwavers prefer digital tuning, the stations ae really packed in close!!! But for a dynamo-powered rig, this seems pretty good.
I suggest that one ask specificallly for model # 12-803--I don't think that the clerk would have known he had any in the store if I hadn't. (To be fair, the clerk at the store that didn't have any dynamo radios had it more together.)
EDIT:
I guess I should say that a Radio Shack Clerk told me it was discontinued. The Web site says:
"Sorry, this item is out of stock in our on-line store. "
There is an 800 number that apparently one could order from according to the site.
Whatever that means.
