3c 1851 Plating Help (Probably Plate 6-8), Please

Hi all.

The cover below recently decided to come live with me. Working on plating the stamp. From the date, I'm figuring that it's likely from the 6-8 range. The main thing I see (aside from the bottom margin), is a gap in the frame line by the upper left triangle.

Given that, the best I can come up with is:
100R6, 91R7, or 100L8.

As inept as I am at plating, I may be way off base.

If someone more competent could confirm the plating of the stamp, I'd appreciate it.

Thanks
Chip

Chip,
Quite posibly the 100L8. I would not say either the 100R6 or 91R7 are a match. The wide margins on the L&R would match a plate 8 stamp. Sadly there are too many bottom row plate 8 stamps missing in the Stamp Smarter Plating Initiative to be definitive from my limited perspective.

Thanks, Paul.

Are you aware of this website: http://stampplating.com/
A link to it is now on the homepage of the USPCS website http://uspcs.org (I think they're also hosting it)

Its not 100L8. The left frameline is way too far away from the UL rosette.

93L7 works well here.
I think I see the vertical recut connecting the UR diamond block to the UR triangle, and also same at bottom right. Top left and top right corners match.

Thanks. I'll take another look.

I agree with 93L7. The Scott #11 Type I's can be fairly readily separated into three groups, Plate 4, Plate 6 or 7, and Plate 8. Plate 8 stamps are fairly distinctive in that the frame lines tend to be very heavily recut, unlike the stamp under discussion here.

Thank you both.
Chip
