I believe this set to be complete. The bricks themselves are in fair condition for their age. There is some wear and age related fading to some of the pieces, as can be expected for a set of this era. Some of the sleeper clips have broken; they go brittle with age.
For the pictures I merely laid the track on them; not clipped in. This will allow me to respond easily. For auctions, please wait for an invoice. 5 weeks Apologies these are Royal Mails rules not mine. In my experience their investigations take a couple of weeks.
