I have a mountain (model W230) It was only recently when I started looking at Martin Guitars, it suddenly occured to me that this guitar I brought in a dickensian guitar shop (long gone!) in a very run down area of Nottingham way back in 1979 !was possibly a Martin copy! Having looked for information I still cannot find any info regarding this model. Strangely enough like the previous contributers I have always felt very attached to this guitar, it has a certain something... I brought it for about £80 which then seemed like a small fortune (on a student grant). Since then it has taken a very bad knock when performing that resulted in a serious crack at the nut between neck and head. It was fixed but appears to be coming away again. Surprisingly it still plays like a dream. Any one any ideas as to Model, history, repair possibilities, value??? Having read the above comments I am now taking much better care of it!!
