Viner frame numbers

[bonzo221983]

I've recently bought a used Viner VSL Carbon Pro Team frame & fork. The numbers stamped on the bb shell are 52 V 91 and T01 01. I know 52 is the size, but does anyone know what the other numbers mean? It has a 1" steerer and the previous owner thought it was from around '97, but going on the numbers on the bb shell, my guess is 2001??

Thanks.
