Electric Furnace ages

I have all the Preston info and the great info from the users on this site for gas appliances and AC exterior units.

I do not have anything for Electric furnaces.

I have a Carrier furnace model number 40AQ030300BU serial number 0886A69122

my guess is a 1986 model.

But I’d like to get a reference guide or cheat sheet if anyone has the information to get this.

Thanks, !!!
