Valve Cover on TR 2 through 4A

[jmwagner <jmwagner@greenheart.com>]

I'm curious...  what other cars, besides the Triumph TR series through
4A, had the same valve cover?

I know that certain Morgans had it... though I'm not sure which ones.
Etc.

I'd like to know, in case I'm missing a market for my current silicone
gasket.  Plus it's just a curiosity!

Thanks.
