Thanks, Lee. For whatever reason, I've been doing the POCA Newsletters since mid-1995.... One of these days, I'll get one perfect and can retire <grin>. When PI had a magazine I used to write exclusive articles for Dave & Linda, too. All just one big family.
On those Mangusta scans, I now believe that they were 'factory done' over a period of time but probably not as formal parts lists, at least not to start with. They likely combined parts of several bundles. The earlier Vallelunga scans are much the same. More likely, someone at DeTomaso Automobili or maybe Ghia said, 'Hey, the car is really selling. We ought to document some of these changes'.... . Going by the Owners Manuals and other published paperwork, it seems DeTomaso didn't really get organized until Ford took over 84% of the operation in 1970 and brought Detroit methods into play.
Y'all realize that even up to the '80s, A. DeTomaso Inc kept one of the latest version of every part they had for sale, as a 'working model'. When the inventory got low, they contacted a supplier and said, 'Make a dozen or so just like this!" Rather than trusting the dwgs to be up to date. Drove us nuts during factory visits when we could SEE the part we needed on the shelf but were told, 'It's our last one. Can't sell that or I'll get fired! Come back in a month and we'll have more". That was seldom an option for private international visitors trying to score a bargain while on vacation. Ahh, the hand-built Italian supercar biz...
