Yeah, it might be easier to search for Araya Alloy 27 x 1 1/4" wheels, with Shimano small flange hubs and QR skewers.

And if you're real lucky you'll find one with the correct 13-28 Gold Altus freewheel like the one I found last week. It was in the back of a group of unidentified wheels and the gold gears just jumped out at me. I asked the seller for closeups of that wheel and confirmed it was the real thing! On it's way here now.

But that was pure luck with a little sleuthing thrown in. I've only seen one other correct wheelset and that was about 8 months ago. Searching for 'Araya 27' will get you in the ballpark though.

Edit: I just looked at your photos again and noticed the original wheelset. What's wrong with them?
