newbie just got his first Bug

Hello people,

I have just obtained my first Bug. On the positive side, the machine was
free. On the negative side its in pieces, has no seat, and the
dismounted engine and transaxel have quite a bit of rust on them.

I've worked on motorcycles and done routine maintenance on my various
cars, but this will be the first time I've actually needed to tear
everything apart and rebuild it from scratch. I've purchased "How to
keep your VW alive" and the Hayes manual, plus I've just ordered all the
'special' tools from one of the online companies (no free publicity
until I see what they're like.)

The vehicle body is a '73 but I have no idea if its a Super Beetle or
not. How can I tell? (If this is in a FAQ, I'll be happy to STFU if you
point me to it.)

The other mystery is that the engine serial number begins with a "1" and
all the other numbers are too faint to see. I'll hopefully be able to
clean enough gunk off the generator pillar to see the number better next
weekend. From what I can find, though, engine numbers beginning with "1"
are pre-1960. This would indicate that it ain't a 1600. Anyone have an
idea on what capacity it could be?

I plan on rebuilding this "on the cheap"; keeping whatever
engine/transaxel that's in the box and rebuilding them myself if
possible. I'd like to avoid buying new ones.

Any tips or suggestions would be appreciated.

Thanks,
Animal
