Hi Warren,

Nice to hear from you but this msg, as you can see, was intended for
Walter and wad not a response to the email I sent you last Sunday.

Since my original msg was sent from your website I don't have a copy
in my machine to resend but I'd still like to get a reply.

Cordially,

Larry Racies
