If you will download the Series 10 catalog from there, in the back, is the 1985
price list addendum - page 4. You will find that the 1031 remained the 1031,
still, but with the halogen bulb. You can see all the illuminor types mentioned
there . . . it seems that at this point, AO had settled on just two -- the 1037,
and the newer bulbed 1031.
