[Public-list] Original gatevalve sizes

[Gordon Laco]

Hello Jack -

I am with Eclisiastical and Larry Fraser is my broker.  I was with Robertson
& Robertson years ago  in my wooden boat days but found a better deal
through a diff broker.

I have not yet settled on a surveyor - I forget where you are.  I am in
Midland on Georgian Bay.

Gord
