Thanks for the reply...
It says DO226679 on the first page of the Owner's Manual. Bertha said she walked to Clarkdale on Nov. 7, 1967 and asked to buy their "cheapest" Beetle. She'd gone in wanting a '67, but was told they only had early '68's at this time....
I talk to her all the time - she's my neighbour, now 87 years old, and I rescued the car from going to the "scrapper"...
Luckily she saved everything - Dealer Plate Frame, Vinyl booklet, and receipts (a lot of dodgy work had been done!)....
I've since replaced the nose as it was crushed and poorly repaired. Went through the doors and removed a lot of rust on the edges, one quarter panel had a hole from rust under the soundproofing tar matt, a few rusty seam issues, front beam was toast, rust in the rear quarters, front drivers heater channel among other things...
Oh, I didn't mention, it has / had a rubber simulated carpet.
Cheers.
