GH,
If you check out this thread in this section named " Larry-have you heard about this one "
http://www.trumpetmaster.com/forums/viewtopic.php?t=931
and read my answer, you'll see that there are no Calicchio's with a serial number from 3100 - 3999. Also the number 3099 dates the trumpet at 1983 which is 3 years past Dominick's death. When I see a " Vintage Calicchio " for sale, I figure that means it a Dominick.
Maybe you can get a picture or url for all of us to look at.
A 2/9 is an excellent combination thou. You should really be able to have a big, wide sound with that one.
If you would like to PM me about it , go ahead, but I like a real name on a PM - that's why it's called a " Personal Message "
