UPDATE: There are more of these five-brochure sets on eBay. View all the info on eBay. These are five out of the 20 issued (Form 600-01 through 600-20) during 1960. Slightly different, but similar brochures were published in 1959 (Form 59-01 through 59-20). The form number can be found at the bottom of the brochures. I’m working on assembling an entire list for each year. 

(02/09/2017) I bought and received a set of these. By the time you factor in the exchange rate, this is a good price.
