Dimensions of various revolver cylinders.

[Jarlath]

I am trying to find out the dimensions of the various revolver cylinders so that I can find an appropriate speedloader for my newfound Mateba...

Looking for the Dimension shown for the following

1. S&W K-Frame
2. S&W 27
3. S&W L-Frame
4. Colt Cobra
5. Colt King Cobra
6. Colt Python

Looking for reasonable accuracy (+/- 0.5mm if possible)

Anyone have them or know where to get them? Thanks.
