It is amazing to think that Ingersoll rand as had no control over the keys for so long ..yet managed to keep the codes and depths & spaces from us or a secret for so long !
Not to mention being a pretty darn nice lock!
I did not write the depth of cut on each of my bittings because I am not sure where the keys are to be measured from on a double-sided key. Measured bit depths to the inner warding on each side of the blade. Are double sided keys just measured down from the edge of the blade?
Maybe I'll get started uploading the pictures of the teardown of an Invinceable, and work on the pictorial write-up that I so clearly hate doing. Have pictures of the levers that might apply here, too.
