OffersTraining bars that came with my Quantum when I bought her a few years ago.
Not a P&M product and you should ensure their suitability/ serviceability with your inspector/ instructor before use.
No guarantee regarding suitability or serviceability, however they appear to be well made and are in fair condition with apparently only minor surface corrosion- see the pictures.

Offers welcome- postage at cost or collection from SW, possible from Swindon, Bristol, Taunton, Exeter or Truro.
I m mobile most weeks.
