Greg,
Thanks for being punctilious enough to include the actual
dimensions. The blades I was asking about were in fact the
29mm x 16mm type.
So now I'm wondering if the "Imperial Oval" name didn't come
into use until the NCO (New Continental Oval) blades came into
existence. Then again, perhaps we should just start referring
to these blades by their dimensions - as Greg did - in order to
avoid confusion.
To be honest, when I first started caring about this stuff
(say 1968) I hadn't yet heard any of these terms. All I ever
heard were terms like "Reynolds size" and "Italian forks". And
I was too dazzled to ask about things such as Durifort or any
of the German stuff.
