Can anyone identify the components circled in black? Weber 6049A Schematic
"Body, tip, and spot".

I can't see the spots, which would usually be on the end (or cap) opposite the tip. But it appears those two resistors are 27x (2700,27k,270k) and 30x(3k,30k etc). 

Which suggests they might be 27k and 30k in the anodes of a phase splitter?

Use a multimeter, bearing in mind they may easily have doubled in resistance from heat and age. It should at least establish which decade they are, if you can't find the spots!

(The brown waxed paper roll underneath will be a capacitor)

Seeing the updated information : yes, if the spot is invisible, it is either the same colour as the body, or fell off long ago. Your measurements are consistent with this : 


Red/Purple/Red = 2.7k, so these have only drifted little more than 10%, and don't need replacement
Orange/Black/Orange, 30K. Resistors in this range are often anode loads, as your schematic shows, and run hot. So it's typical for them to increase quite a lot (35 or 42k are well within expectations, and still usable, but worth replacing if you want original performance.
Bromn/black/green = 1 Meg. These tended to be lightly loaded, e.g. a grid leak taking only microamps, and sure enough its value is still spot on.
