Pics would still be nice. Dave Scrimshaw doesn't have many Typhoons of this vintage on his data base.
As Midlife says Reynolds or Kromo were the options.Typhoon was advertised as being " within the reach of the man who must watch his expenditure"! Certainly in later years the Typhoon was plain gauge Reynolds ( I have a '65) although I have noticed back in 50's they used more DB throughout model range. Do you know what size seat post your new frame takes?
Interesting it was purchased in 1952. That is a valuable document to have! Do you have a copy? Wonder what exact date in 1952 purchase took place? Does document say if it is a 1952 model? Often there was a delay of a year between being put up for sale and actual purchase. It would be nice to see a pic of document and would be great to add to Dave's database.
Like I said in prior post, number 16218, according to Dave's present prediction graph, places in 1951. However there is evidence with good examples on Classic Lightweights to show that 16xxx's numbers belong in 1952. I understand Dave is going to be revising his prediction graph in near future and your frame's number will indeed fit in 1952 according to updated prediction table.
Intersting to see where fender eyes are placed on your frame? One difference I noted in catalog pics from year of Typhoon introduction in 1951 and 1952 was that fender eyes were moved from higher up on stays to down by dropouts. Wonder re yours?
Again some pics of frame would be great to see.
