Both came to bethel before 1992, the last year of Friedrich Franz. they are overlappers.
* Please file your brain away as 'not required' when reading the following:-
Not necessarily. Being at Bethel doesn't indicate you are anointed.
An over-lapper could be anywhere in the world if they were anointed before any of the pre-1914 anointed died (such as F. Franz in 1992).
To be a young person claiming to be anointed in the late 80s or 90s you'd have been viewed with extreme suspicion. Certainly Ken Cook didn't claim to be anointed until the 2000's when he arrived back in Bethel. It's a career move. I'd lay money on the same being true of Flegel and Winder. They're almost certainly not of "this generation" via the over-lapping side hustle.
N.B. As far as I understand it GB helpers don't have to be anointed, but they may be anointed. I.e. anyone can be a GB helper (any male that is).
