If you are ever in Birmingham, AL, check out the Barber museum. I was there in 2005, and they had a 69 H1 on display. Their bike was perfectly restored, gorgeous. But it wasn't an early bike, the engine case had numbers over 4000 if I recall correctly.
I had a beat up old 69 H1 that I never rode, I used to ride it every day back in college, but it had been sitting in my shop since I moved back from CA to FL in 82. My bike had frame and engine numbers less than 600. Mine was far from perfect, the seat had died in the 70s and I made a cafe-ish seat, the shiny bits disappeared, the forks were bent when I got it so I replaced the forks and wheels with H2 bits. Akront shoulderless rims, stainless spokes, Denco chambers, Datsun ignition...basic rat rod bike, fun in a straight line.
After seeing that bike in the museum, when I got back to Florida, I blew the dust off my bike, cleaned the carbs, put in a battery, fired it up ring ding ding. I sent an email to Barber, asked them if they wanted my old bike, when I told them it was an early one they said they would take it sight unseen, sent a truck to Florida to collect it. They gave me a form to fill out, so I could claim a tax deduction for a charitable donation.
They probably pulled a couple parts off it and threw the rest in a dumpster. But hey, if you haven't sold your old bike, and you don't want to mess with it, maybe you could donate it to charity like I did, take the IRS deduction.
