Everythings coming up Milhouse!
Huh. I couldn't see what was different about the heater in the pictures back a page, but now that you mention it the screen is noticeably more convex. It looks like the heater is an 18mm female to 18mm female with the coils and boro tubes inside of it. Maybe the 18mm to 18mm female glass piece is a little different.
