I also have a CF MOUNTAIN. I love it to pieces, it sound really great to play, got a good rich sound, loud without being over bearing. it was bought for me when I was 14 by my parents for me back in the mid 80's from a guitar shop in Bristol, England. it was 2nd hand then, it is a W120 model I think, it is hard to read as it hasn't been printed on the label very clearly. it is so funny when people come to the house you should see their faces when they think from a distance it is a martin, I would love to own a martin so I could compare the two, but from what I have read on other sites, the mountain does sound better. I cant imagine ever wanting to sell it, as it is quite sentimental to me.
