It looks fine, although I would move the two wider filters a bit to the right. 
There looks like about 6-8 db difference in attenuation between the widest and 
narrowest filters, which is probably on the high side of normal (although this 
tends to vary).  I see about 4 db on mine, which is #709 but has had the 
crystals replaced and T7 rewound to current spec.

I would be interested in knowing how much difference in attenuation others are 
seeing.  I know that K1JD has an ANCIENT K2 (field test vintage) which has zero 
db difference!
