We're fans of 'old-speed' style tuning goodies and so we've decided to pep up the motor with some vintage tuning stuff. The question then is which way and how far to go.
There is not a lot out there about vintage speed (or 'Old Speed' as it is sometimes known), but from doing a LOT of reading old VW magazines and tuning books and digging around some really good websites, it seems like there are 3 basic directions that you can go in when building a vintage speed VW motor to be period-correct, up to about 1969 at least:

1 - increase the cc of the motor only
2 - vintage twin carburetor set-up
or 3 - a vintage supercharger
This is twin-carb kit made by Okrasa - this one is a TSV-1300/34, made for the 34hp 1200 (like ours) which means that as well as the twin carbs, manifolds and very smart twin-port heads, it also came with the Okrasa 69.5mm crank, which increased capacity to 1300 (pic from May 1965 issue of Safer Motoring).
This is a Shorrock Supercharger for a VW 1200 offering a '50%' increase in power. Ad from 1965.
We've decided to go down the carburetor and increased cc route - more to come on that soon.
