Imperial oval blades were most often found on British bikes and may help narrow down the origin of your frame. N.B. Reynolds supplied blades in either profile, but most other tubing manufacturers only supplied "Continental" profile.

so I dont have a caliper but using a vice grip i'm measuring the long axis at about 28.575mm and the short axis at 9.525mm
