FWIW...my riders are a new pro, and old pro, a B17, a B17 Champion
Narrow, a Swift, a 1961 Middlemore Swallow, and a not yet ridden old
NOS B15 Swallow.
My fave is the Middlemore...
I cannot find a date on the Brooks Swallow...does that imply a date or
time period? There is a bizarre mark in red on the leather but it is
rather cryptic.
