Ids For Three US Stamps Pleez!

(1) This is, I think, Scott #220, but it has two sides imperf. Is there a booklet stamp variety?



(2) A 1c green Franklin with vertical double line USPS watermark:



and (3) A really odd looking perfin:



Does anyone know what the motif is (excuse the breadcrumb)?

The first one is a 220 as you said can't see any signs of booklets but on the earlyer stamps the edges of the sheets were not perforated and this is the top right corner of the sheet
The next one is a 279 and the line and Imperf is a guide line for splitting the sheet in to smaller sheets but I have not seen it on this issue before and the sheet I looked at didn't have it (doesn't mean its not common just a new one on mebut someone will answer this)
The other is a 814 Got no idea about the perfin I got about 300 in a book and no idea

Thanks for taking the trouble to look, razersedge!
