Giant, it looks like my ignorance was profitable. The listing claimed the item came with the canvass cover and the DM Exterior box. When it arrived I got the styrofoam and velcro strap but not the original outer white box (and I guess now I know why there was no canvass, either). I messaged the seller and said excuse me, your listing said these two items I didn't get, and he refunded $40 of my money. I don't feel too bad, because he did claim it came with the box and I know that can affect price by at least $20 or more. It's also very good to know about the top. I really did think it was supposed to have one until just now, so thanks for the info.
Thanks, Shaun, ya learn somethin' new every day, eh? I'm thinkin' about a Model T pickup, too. Just missed one for 20 bucks, but got beat out by half a dollar.
Now I just need it to dry up outside so I can use all this stuff.

When FDR coined the phrase "The Arsenal of Democracy", he was talking about Detroit. Proud to live in the 2nd most violent city in America!!
