Trying To Differentiate Three Brooklyn $1 #571

Can anyone tell me what these are:

The left: Brooklyn with comma centered above N.Y. with no repeats of either word.

The center: as above, no comma, but is that just because it's faint?
Also, it's angled slightly -- is that a type or just a clumsy HS? With the angle, it's hard to tell, but I *think* it's the same width between lines as the left one.

The right: BrooklynBrooklyn repeated, with N.Y. (centered once under each town name?). There is a weird comma-like mark on the right, seemingly unconnected to the rest of the printing?

I can't find anything that seems to match in PSS T&T?

Cheers.

These all look like L16's... the left stamp has the tail-on-R variety.

chasa -- Thanks.

So do you think the two on the left are just from an area of the sheet that didn't get the continuous BrooklynBrooklyn effect? (the right hand edge, maybe?)

Also -- I have never heard of the tail on R, although I can see it now you pointed it out. I don't collect "errors"/"variants", but I do have to check with you that it isn't unusual (i.e. rare!) ??
