Pirelli do have a Vintage range. I bought a set for my Pursang MK4 restoration.
They are MT16 Gara Cross,they come in old sizes 4.00 X 18 and 3.00 x 21.
The pattern is old style,chunky knobbly as well. Reasonably priced at $100 rear and $90 front.They are made in Brazil.
I think you can see them on the Linx website
