Hi John,
Welcome to the forum.
As I'm sure you are aware the post you responded to is 13 years old and the author redkop was last active on the site in July 2022, so you may not get a response. As you can't send a pm to redkop until you have made 5(?) posts, I've taken the liberty of pming him on your behalf, in the hope that he will get an email notifying him about the pm.
