The concentric rings on f57v...?

[Nick Pelling <incoming@xxxxxxxxxxxxxxxxx>]

Hi everyone,

On the monochrome image I'm looking at of f57v (the page with the four 
concentric rings), there are four straight lines emerging roughly from the 
centre: the character immediately clockwise from these lines on the 
penultimate ring of letters [the ring of 4 x 16 single characters] is 
always "o".

My question is: does it look like those four lines were part of the 
original page design?

It's *really* hard to tell from the picture I have here. :-(

Thanks very much, .....Nick Pelling.....
