Batavus Professional 56.5 x 56.5 w/ seatpost issue

Batavus Professional frame / forks *

I bought in 2013 from an old postie building bikes with his retirement.

pearl and blue
I think 1984
56.5 x 56.5 (stamped 58 on bb)
Columbus SL tubing i think, decal is worn, across the web many claim different types.
Piet Nizet decals..
Stronglight headset (i bought new around 4 years ago) one replacement sealed bearing included

• Unfortunately 😓 this has a seized seatpost. I’ve tried everything, but the caustic soda method (the paint😖). I’ve even taken it to this guy (https://www.stirlingbikedoctor.co.uk/seized-seatpost-removal/) who couldn’t do it on his machine, but says it should come out manually sawing. The price i think reflects the cost minus what he quotes for manual removal (£90)
  
  

So if you feel like having a go removing it yourself, or just riding it as is - i’ll include a replacement 27mm seatpost.

Let me know if you want to know anything else.

Based in Glasgow, happy to post, happy to meet
