Martin ukulele identification

I have seen a Martin ukulele locally and am wondering what model it is. It has the following attributes:
1. 14 frets to the body
2. C.F. Martin decal on the front of the headstock
3. single dot inlays on the 5th, 7th and 10th frets
4. double dot inlay at the 12th fret
5. mahogany body

I have looked at dozens of pictures of Martin ukuleles but cannot identify it.
Any ideas?

Thanks in advance

Most likely a style "O" pre 1962...........Howie

if it's 14 frets to the body with double dot inlays, it sounds like a tenor to me.

style 0's don't have double dot inlays and should be 12 frets to the body

Thanks for the replies. I think it is a 14 fret T-1. This url shows a Martin T-1 that looks exactly what I was attempting to describe:

Are Martin 14-fret T-1 ukuleles particularly collectible? Any idea of the period Martin was making them?
