Engraved 2cents2 Possible Scott#406, Please?

Hi All!
Below are the images of an engraved 2cents2. One can feel the lines of engraving with the finger-nail. It is a darker bright carmine color.
The dimension of the design is 18.5x22mm. It seems to be Type I - not Ia etc.
Fiddling with the image editor I see some lines which look like watermarks mainly above the left 2 (of the black and white picture), but I have no idea what they are.
[I uploaded the front of the stamp with same gradients of black and white only to show the small '1' in the fourth line of the cancellation, above the ear. I guess that is something having to do with the type of the machine used.]
Is the stamp a Scott#406, please?
Perforations are 12x12 in a 20mm segment.
Thank you very much!

Yes, 406. Since it is a perf 12 sheet stamp, there are no other possibilities. It is Type I, will be engraved and have a single line watermark.

I don't know what source you are using to determine catalog numbers, but identifying the Washington/Franklin issues can be intimidating at first. The introductory pages of the Scott US Specialized has a nice identifier section for definitive. It is roughly grouped by sheets, coils, imperfs, then by perforation rate, then by type.

When faced with a pile of 2 cent W/F issue, I separate out the coils, imperfs, and offset printings by sight then approach the perforation rate of the remaining pile of sheet/booklet stamps. Then typing if needed. Watermarking is last, also if needed. I find there is little need to measure the size of the printed image. Perhaps others will share their identification schemes. It is also helpful if you have a considerable quantity of these stamps - to learn by direct comparison, rather than secondary sources.

This tool lets you identify most Washington/Franklin stamps within three steps http://stampsmarter.com/features/SQ...rank_ID.html
