My grandfather had a Hup in his youth and we cast about the net a few times seeing if we could find a few photos, parts, classifieds, etc... ended up (sometime after visiting your site, iirc) going on a day trip to see a Kaiser museum in Nebraska or something - dozens of them, fully restored and pretty impressive. Amazing what lies hidden around the globe, small or not ;)
Take care, and if you're bored, take a peep at
http://www.drivingbargains.com for a chuckle at how badly MY pages link together sometimes, heh. Ah, the "fun" sites never get the attention they deserve. Oh well. Someday!
