WTD: Stems, bars, fixed/free 36h, brake levers, freewheel, cog, gumwall tyres, 16-20" wheel

What is up my people?!

I'm looking these parts for my fixed/SS conversion:

• 36h fixed free hub, silver, low flange would be nice but will consider anything
  
• Brake levers, silver, for caliper brakes, something like Cane Creek or Condor
  
• Freewheel, 19t (maybe 18t), Shimano/Halo type quality
  
• Fixed cog and lockring, 19t (maybe 18t)
  
• Gumwall tyres x2 (lighter/blonde, not brown) 23mm
  
  

...finally for a trailer project:

• 16" front wheel, 100mm hub, with tyre if possible
  
  

(Tandem parts all sorted now thanks.)
