1952 Topps #131-190 Gray Backs

[usmcloady]

Hello everyone. First time poster, long time reader. My name is Sean and I am a Collector of several different items (Vintage Cards, Modern Cards, Toy Collectables). I have read this thread several times as I have been trying to find information on the 1952 Grey Backs and their possible connection to Topps Rails and Sails. I know collectors recall finding 52' Grey backs in Rails and Sails packs, but the majority of the Rails and Sails packs I have seen are from 1955. I have, however, also seen 1953 Topps Rails and Sails packs (OPC or Printed in Canada??). Is it possible that the Rails and Sails packs were sold in 1953 and 1955 (I have never seen a 1954 Rails and Sails pack)? 1953 being very close to the 1952 Topps run thus providing a possible method for distribution of 1952 Greys in 1953 Rails and Sails packs? This is just something I have been mulling over in my head recently and thought I post it here for the knowledgeable collectors here on the board. In my head, this seems very possible, a 1953 Topps Rails and Sails pack containing some extra cards from a previous print run to "Fatten" the packs up. Has anyone ever opened/or know of someone opening a 1955 or 1953 Rails and Sails pack in the past, say, 10 years?
