700c narrow clincher tires came onto the scene in the later 1970's as I remember, and by 1990 I don't think any, but perhaps a generic Taiwan bike with steel rims, had 27" rms any more.
Narrow 27" tires are now a scarce commodity, and no premium racing tires are now made in the 27" size. There are many good 27" tires still available however, but most are only as narrow as 26mm when described as 27 X 1-1/8".
The Panaracer Pasela, IRC Road Winner and Continental GatorSkin come to mind as the higher-quality offerings in the 27" size, but there are very many others that are at least good.
