I have a file binder which is inscribed "This is a Peterson binder for International Standard A-4 size sheet 11-3/4" x 8-1/4". The metal is a 4 ring "D" style, 1-1/2 inch capacity. Manufactured by The Chas. Chapman Co. Ltd. London - Ontario. Est. 1855" I don't know if this product ever went into productioin or appeared in the shops. I also have an adjustable 4-hole punch that can be adjusted to 8, 8, 8 cm to punch the file bbinder. The only indentification on it is "Japan". For envelopes I use 4-5/8" by 6-3/4' (117 by 171 mm) instead of ISO size C6 = 114 by 162 mm; and #10 = 4-1/8" by 9-1/2" (105 by 241 mm) instead of ISO DL = 110 by 220 mm. I forgot to mention that the aspect ratio of all the ISO paper sizes is 1 : sq. root 2. With the P an Q series the aspect ratios fluctuate from less than sq. root 2 to greater than sq. root 2. The result is that an advertisemnt that fits a P4 page can not be reduced to fit a P5 page. This is in contrast with the ISO sizes. An advertisement that fits A4 can be reduced to exactly fit A5 or B5 and enlarged to fit A3 or B4 Joseph B. Reid 17 Glebe Road West Toronto M5P 1C8 Tel. 416 486-6071
