You're welcome, John. It's what I'm here to do.
Dave, I do not recall seeing a US-made Bormann fuze with a "high lip." But I've seen a few (just a very-very few)l CS-made ones which do not have the "high lip" (which some folks more descriptively call a "non-threaded lip").
So, the absence of a high-lip/non-threaded-lip is not quite a 100% accurate indicator that a Bormann fuze is US-made.
Still, this is the right place to ask, has anybody seen a US-made Bormann fuze which has the high-lip/non-threaded-lip? Mike? Carl?
Regards,
Pete
