Those frame are far from rubbish .. Principia's where handmade with custom to Principia tubing and they are regarded as probably the very best Alloy frames you could buy at the time - the Danish track team used a similar frame to the one advertised - any defect in the finish or the perfect tig welds and the frame was rejected by the craftsmen making them in Denmark, which is believed to be why they went bust!
Principia make absolutely superb high end alu track racing frames. Don't buy it though if your sick of you 60's British steel frame and are looking for an upgrade to ride around London. Pure racing machines these.

Principia frames are an alu/viagra mix ;)
