Double check that frame number especially on the steerer tube. If it reads 3258LE then it`s an Ephgrave built 1959/60. Les Ephgrave`s No. 1 lugwork could be mistaken for Holdsworth`s Monsoon. And if it is an Ephgrave then forget about Holdsworth - the dog you`ve bought has got real pedigree!!!
P.S. Just got onto CR List so hi and thanks for warm welcome to all I met at this years Cirque.
