I've been trying to find a font to match the font used for "RICH" in this logo and I can't find it. I need to do a few logos based on this and it's so old that no one knows anything about it basically. They've just been using it for years. If anyone could help or even give me the name of a font that I could modify to make it work would be great. All I need is a few letters to match up (R I C H M S $).

Thank You. I really appreciate the help. I was about to give up.
