That last Tektronix 2252 Operators Manual (PDF) put in as 070-7837-00.pdf is the exact same BAD OCR copy that ends at page 4-6, as the other two copies at the end of the list. We should remove the last two copies and mention in the description of the top one that it's "bad-OCR ends at page 4-6". --Jyohe (talk) 23:41, 4 June 2019 (PDT)
