I cannot address your questions directly, but I can provide some information that may fill in details about his lifestyle.
My ex-wife's immediate family (her grandparents immigrated from Lebanon to Jamaica around the time of WW I) was originally from Jamaica (West Indies). Her father was a very successful businessman and they lived a very comfortable life with servants, a chauffer, and all of the other advantages of wealth. My ex's extended family (aunts and uncles) were all very successful as well and some of them who were not Dubs were politically influential as well.
Whenever Knorr visited Jamaica (1950s and 1960s) he stayed at my ex's home and enjoyed the lifestyle my father-in-law provided for him and his wife -- fine dining, the best of new clothes, the chauffered car, etc.--anything they wanted. Other Bethel "heavies" were treated equally well by other members of my ex's extended family. I cannot categorically say, to what degree Knorr and the other influential Bethel "heavies" were given cash (although, that they definitely received plenty of it), I can say that they all lacked for nothing. All of them got first class treatment and accomodations wherever they went.
Just to put this in perspective, my father-in-law was not an ass-kisser--he was a genuinely good, righteous man (although totally misguided as all of us were when we were in the BORG). However, there were plenty of other wealthy Dubs who I thought were total ass-kissers and sought out association with the Bethel and Branch "heavies" as a source of prestige. Some have discussed Harry Peloyan on this board--he was one of those who was treated like a king by ex's extended family.
I think it is safe to say that the Knorr, Franz, and the other high-command lived a millionaire's lifestyle when they were travelling, even if they gave the outward appearance of modest living while they were at HQ in New York.
I hope this is at least helpful.
