approx 4 inch barrel lengths

[Edward Tinker]

I had a barrel taken off and new one put on by GT () and then when I went to put them in my parts chest, I found one did not fit.

We always hear about the slight variation in sizes, but remember that at one time the barrels were actually changed in length.

Top is a 30 luger and has Crown N marking on it - sn 1783k
Middle is the odd one, 9mm sn 4876 with an 8 just under the sn and in a line up, looks almost like Crown B and then Crown V
Bottom is a Eagle 655, 9mm, 5859 (import marked)
