Hi Paul,
Sorry for the delay. My cubby is crap. Not bad condition, just a very old one, with no cup holders or anything. I've not seen another like it actually, I guess in an ex-MOD one. I'm not sure it's what you will be after.
Shame about the seat. I really need one that fits together, as it's going to be used a fair bit, and I don't want to run the risk of it falling apart!
