Subject: [CR]'49 R O Harrison Shortwin...what a strange seat tube!

I am on the UK Classic light Weights site looking at a bike called a R O Harrison Shortwin. The year seems seems a bit uncertain being given in the URL as 1947 and on the caption as 1949. http://www.classiclightweights.co.uk/ROHarrisonShortwin1947.html This has the seat tube joining the down tube a couple of inches forward of the bottom bracket shell. This gives a very strange angle to the seat tube. I am wondering if this is unique to this maker? Is there a logic for this arrangement that escapes me? Perhaps some of our Brit members has some light to shed on this? Never seen such an arrangement before.
