Question About Chicago Cancel

Ok, can anyone help with an approximate date when this cross cancel was used in Chicago? There is no backstamp from Pa. Thanks !

In James M. Cole's "Cancellations and Killers of the Banknote Era 1870-1894" I found the cancel on the cover you show. Mr. Cole assigns a catalog number of CSU-30 to this cancel and gives it a rarity factor of "I" which means it is common. The illustration of the cancel in Mr. Cole's book/catalog is more worn looking than the one on your cover. He lists it as being a blue cancel used in Chicago and his illustration comes from an 1874 cover. Dave

Found it.......CSU-30, 1874.

Thanks Dave !

Your cover has a sharper looking example of the cancel before it became worn down some from usage. Dave

All of Cole's cancels (and more) are listed in this online database

Thanks Don,.......I finally found it on Stamp Smarter. Dave, yes......its a real nice one for the cost.....LOL, got a whole plastic zip lock bag full of old covers for 3 bucks. Must have been about 35 covers in there all pre 1920!
