The Computer History Museum (Mountain View, California) has the most 
extensive collection of IBM 1620 items - hardware, manuals, books, 
software, etc. - in the world.  Most of the items were collected a 
number of years ago when a team of volunteers restored the museum's IBM 
1620 Model 1 Level F computer to full operation.

I verified that the museum has both of these physical manuals, plus some 
associated update notices.  So, the museum does not need them.  Thanks 
for offering.

A subset of the restoration team is currently building a historic 
replica of the machine - dubbed the IBM 1620 Jr. - for the museum's 
education department use.  We've exhibited it at VCF West the past 2 
years [winning Best in Show last year] and will be there again this 
year.  This year we will be highlighting our work to create a 
general-purpose, ASCII terminal using an IBM/Lexmark Wheelwriter 1000
