Could This Be A Part Of The Horiz. Pair, Imperf Between?

No. In order to have an imperf between stamps certified they must be an attached pair. It looks as if it was an off-centered Stamp with the perfs torn off the right side, or possibly from a cut line on the sheet.

The short answer: No.

Scott does not list this stamp as existing "imperf between". Even if it did exist, it would have to be a complete pair of stamps to qualify since all stamps printed during this era have the potential for a straight edge if located on the sheet margin.

Thanks!

It has been a pretty hard job to torn all the perfs, is someone did that...

I think your stamp is a normal straight edge from the left pane. It was not uncommon for these to fray over time and develop a ragged appearance. I agree that the right edge is pretty roughed up for a natural straight edge, but they do get that way. Take a look at the right stamp in this pic.



I don't think your stamp was faked from a fully perforated stamp. The plate layout for these was two panes of 100 side by side. When a full sheet of 200 was perforated, they did not run any perforations down the gutter between the right and left panes. The stamp producers cut the panes apart down that gutter resulting in straight edge stamps to the right or left of the cut line. Notice the upper and lower guide arrows in the pic above.

For the steamer plate tests of 1885 some sheets were produced and perforated but left uncut. From these come the cross gutter pairs which have the appearance of being imperf between. Here is such a pair:



These pairs are listed in Scott as 211Bc, but they come from the test sheets which were not regularly issued and do not normally come used. The presence of a cancel is pretty good indication that yours is a regular margin example of Scott #210 from the left pane.

Thank you very much for the complete expertize, Essayk! :-)

Essayk,

Thank you for the lesson! Great information once again.
