Schwinn... heresy !
I suffer from being in a place where there is an abundance of old Raleigh and Raleigh's captive brands like Phillip's and a shortage of Schwinn's... I have never seen a Paramount in real life but have seen many of Raleigh's Carlton built offerings.
Because of this the 26 tpi issue is really not the issue it is in the US where English made Raleighs tend to be rarer birds.
My little herd of Raleighs... this will surely inspire Pastor Bob to post much "better" looking bikes but they still won't be Raleighs.

1955 Lenton Sports, Reg Harris road model, double stepped fixed gear. Can you say 'holy grail" ?

1973 Raleigh Carlton Gran Sport - when you just have the need for speed.

1972 Phillips 20 folder - modified

1978 Raleigh Superbe - my jewel.

1954 Raleigh Sports 3 speed road bike - original

My other Phillip's 20 - modified
And you have to start them early...my daughter's 1971 3 speed which I am quite sure is a Raleigh.
