Just wanted to confirm that it does appear to be Scott catalogue
number RB4.

Another option instead of checking a current Scott catalogue is to
see what it is available for at a dealer's site. For example, Eric
Jackson ( http://www.ericjackson.com/ ) has copies available for
sale from $12.50 to $21.00.

Thank you very much, Rich, for going out of your way to provide the
exact information I needed.

I would never have found that above terrific website.

Since my stamp is damaged (white spots), it's probably worthless and I
can give it away.

This ends our discussion about this topic. I want to thank again Stan,
Richard, Sir F.A. Rien, and especially you, Rich.
