Pickle Cars on the Q

[GEU30CG@a...]

Recently a friend of mine who models the early (1920s) B&O told me that the 
CB&Q operated a small fleet of pickle barrel cars. I have not seen any 
information on these cars. 

Is there photos that exist? How late did they run? Has any issue of the 
Bulletin ran an article on these cars? 

Thanks,
