I'm getting ready to take delivery of a Mathis mount this month.
I have been trawling the net for users of Mathis Instruments mounts, advising them that I have started a Mathis Mount Users Group at YahooGroups:
http://tech.groups.yahoo.com/group/mathisusers/
I hope to see some Mathis mount users there.
Clear Skies!
