Now that's interesting on the 15" Carbine.
My brother found one in Alaska or Yukon(can't remember) but it was a 93 in 30-30 about 15yrs ago. It was only in decent shape, so he peddled it to a bud of mine, who latter sold it to a US collector for $1,500.
I remember at the time it was reported to be rare in baby carbine version. If memory serves me correct(& it may not) I thought the number was 64 or something like that.
Now a baby carbine in 95 in 33wcf
