Radius 103 black wheel brass top

Here is some pre fettel pictures of the Radius 103 i got ahold of for less then 10£. Not original glass but seems to be in working order.

 

And here is the post fettle pictures. Note the distance jet/preheat tube. That dont feel right. Anyone know the correct gap?

 

Turns out the mixingtube needs replacing due to worn threads. That was why the distance was off.

However, differences between this lantern and the other 103 i got(plastic wheel red top) is..
*a small dish is mounted above the flamespreaderchamber.
*the strides in the pumplid is only horizontal.
*Black fiber wheel
*Brass top
*Adjustingnuts on mixingtube are hexagonal.(square on red top)

 

After some special fixing lighting was possible.
