Hello hoping to help as with the 144`s you can`t get a chainring smaller than 41 to fit, due to the length of the arms. You might be lucky to get a 41 T.A. one - very good quality but not very common I`m afraid.
I have a 54 Super Record in vgc. Used for a handful of time trials many years ago. £15 posted. Can get pictures tomorrow if you're interested. I have a 55 too.

Pics as promised. Note these are not new, and have been lightly used but have very little wear to the teeth. Some slight marking from the chain on the rear. I've tried to show this on the final picture.
