I started with a china 500hk .. then got a 1960 828 wow nice quality ...
I was looking for a brass petro and found a old 821 ( i think ) its a 250 indead - but with a "unoriginal" #121 glassholder - so no type shield.
My questions are - I took it apart and discovered the nozzel is a 500 ??
it burns with a pelam 200/300 hk mantel and actually look fine -
But it gets pretty hot on the tank ...
My question is what parts are the difference with the 250 350 and 500 ...
Is it the diameter of the #50 nipplel , size of mantel, and cleaning needle only ??
what about the ceramic thing its obvious of various size ..
And what if one where to use a 500 nipplel and a 500 mantel on a 250..
would it over heat ???
And if i used a 250 nipple and 250 mantel on my 828er would it light less and use less fuel ...
I cant believe I had to live for almos 40 years before i was introduced to these lamps ... I love em
