I will try and photograph these odd ones I see when I see them. albeit not  
that often.

Having  been handed sealed SB-220 and 221 boxes at Heathkit stores I can 
say 
that  I have seen 220's with wide spaced caps and never a 221 without  them.

The very late 220 chassis will have holes for both caps as did a  few 221's 
Ive seen so I have to assume the transition used up whatever was  available.

I cant comment on the transformer plug for sure but Im  fairly confident 
that 
was a 220 chasis with 221 labels and again using up  everything available. 
Photos would help.

Having had well over 400  SB-220 thru HL-2200's go thru my hands since it 
was 
introduced for  construction, repairs and 6M conversions Ive probably seen 
more than most.  But that doesnt mean I havent forgot a few things  either.
