Dayrl,
I saw a basket case Baker action that the blocks would fall out of position when the action was turned upside down. Perhaps the mechanism was worn enough to allow that? Sorry if I mistook that for how they all operate.
In any case, they are not "intercepting sears". Different device, entirely.
Do you have a good photo of a correctly funtioning graded Baker action? I'd love to see it.

Best,
Ted
