Transportation Double Transfer

Here is a neat find. I was looking through some kiloware and this one popped up. US 1897A with indications of a Double Transfer, or an upper section Re-Entry. What do you think?

All the extra lines are in the same direction and position relative to the complete impression, and it is an engraved stamp, so it does appear to be a double transfer. Probably a slip transfer that occurred when the original position was entered. Finding another example from the same position would clinch it.

Check to make sure the stamp is not an untagged error. If tagged, it might be weak ghost tagging -- I think I see the same effect along much of the upper part of the engine. Ghost tagging is not uncommon for US stamps of the 1960s through 1980s. Hard to say for sure in this case. Can you post a closeup of the top half of the engine, and also the back of the train (part above the wheels)?

Here's as close as I can get. I don't have any "tagging" detection items, but, hopefully, you can help out with these closeups. Thanks in advance.

It's a little tough because of the cancel, but there does appear to be numerous signs of a blurred and shifted secondary image. There is an old thread on ghost tagging on SCF. I'll see if I can find/post the link.

Well, I was only able to find these two. The one I was thinking of I may have posted on another Forum (which has since undergone a complete purge of old posts )

This phenomenon is called "Chill roller doubling". On the old Cottrell presses a dryer unit was installed near the end of the printing unit. Sometimes the "Chill Roller" picks up the wet ink from the web and deposits it on another stamp. "Chill Roller Doubling" is more commonly seen on the Transportation stamps that were printed on the old Cottrells because there is so much "white space" on those stamps.

So, keep my day job?

Thanks for the responses. I learn something new every day.

Thanks, Peter! I figure it had to be something similar to ghost tagging.
