How Far Do Cancels Run..?

Hi guys..Got quite a few of these stamps and was looking at a cancel running 5 stamps wide..Does this cancel on a roller OR is it a precancel..?

Looks like a Detroit cancel.

Thanks, Robert







Or these cancels..?




Or fancier cancels..?

It is a roller so it can go as far as the ink will carry it.

Wert - 51Studebaker is correct in confirming that the wavy line "DETROIT MICH. (1)" is from a self-inking roller cancel. The number identifies the PO and I have seen several different numbers.

The CDS is not from a roller. Those are from a standard duplex station canceller. In your examples, you have 1 and 3 in the lozenge. Unfortunately, my information on which numbers go with which PO is packed away. Maybe someone else has that information for us.

Those are very nice strips and I would keep them intact were they in my collection.
