I have an X-Wing. It came from a Palitoy loft find and is unused with decal sheet but is missing cannons and instructions etc. There all still up in the loft somewhere. Pm me if it could be of interest.
My grandfather Designed Palitoy's Finished Goods warehouse - read my research here.
I have a Jedi boxed x wing. X wing is complete and has no yellowing. Box is very good with only minimal edge wear and good corners. No instructions or inserts. PM me for pics if you're interested, cheers
