I happened to be in an older ACE hardware store yesterday that used to sell/service Wheelhorse-then Toro equiopement. They had several left over spray cans on a back shelf. Well -seems like the numbers have changed--I don't know what the dealer has now, but these are labeled:

#361-1 Apple red (for older tractors)
#361-10 New Red (I don't know where the year break is--nobody there even knew how long they had them)
