Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

@eec1910 So is that iron part, between the shield and brass, part of the original heater?  I know on the B-31 I have is missing the bottom mounting plate & power terminals.  I am trying to figure out if I should take @komet163b advise to keep it and get it running.  It is a way cool engine I have to say... 

Here is what I have for the bottom heater - I pulled out the "clamps" which had the mica/heater strip in the hole.  I just don't know if there was suppose to be an iron core or something in there too (or it was just an open hole).

Here is are two photos after I got that heater stuff out and clean her up a wee bit.
