History of engine 195 Inter s/n 0091S

Hello to everybody,
my name is Jonathan from Germany.
I am trying to research the engine of 195 Inter s/n 0091S.
According to Marcel Massini's Vignale book it spent time with Larry Knaack in Illinois, then went on to Gary Schonwald who passed it onto Robert Rubin and then eventually to an unidentified Mr. Carin.
To me it seems as this is incorrect and Schonwald sold the engine from s/n 0083S to Robert Rubin for his 212 Inter s/n 0179EL.
If this is correct and the engines 83 and 91 were mixed up in the records then the engine from s/n 0091S would have ended up with Bernard Worth.
Any comments? Anbody knows where s/n 0091S' engine is today or could have gone to from Bernard Worth?

Best,
Jonathan
