      I found it, right over the pilot light, its an O-12. 
I am not sure why I missed the number before but its in 
quite small print. Anyway, I found a schematic and specs on

beginning in 1958. Mine seems to work other than the spot 
shape control has become intermittant and will have to be 
replaced.
