Thanks a lot for this comparison picture. Very instructive.I found the photo, Heym 89 and the original Gibbs, it doesn’t get more authentic than that.

I must admit that the Gibbs, "stocked to the fences" is more attractive to me than the Heym.
Perhaps an engineer could enlighten us concerning the reason Heym went with their design. Is it sturdier?
Just looking from the pictures, it also seems that for the Gibbs due to this stocking to the fences, the breaches are closer forward of the triggers. Or in other words, the weight of the action should be more back "between the hands". Any expert would like to give their take on this?
