The 158 is found with two different types of burners. One is fitted with the 4115 stove burner (as used on the no.15 stove) and is called the 158/15. The other uses the 4047 stove burner (as used on the no. 107 stove) and just uses the number 158. These heaters use the same tank and basic style of the discontnued 1011 so have a 1.75 litre tank. The heaters could be ordered in three different variations. /1 - nickel plated tank with nickel plated brass reflector. /2 - nickel plated tank with polished aluminium reflector. /3 - nickel plated tank with polished copper reflector. This heater is the 158/15 version with the /3 option. It is from 1938 (AC 19). Note that it was standard for the copper reflectors to be painted black on the back. This example has almost none of the original nickel left on the tank.
