Legacy audit

Many years ago i had a series of OO gauge layouts but in my early 20s i put everything away in boxes ready for when i had my own house so could start again. "Starting again" took me nearly 13 years and in the end i have gone for a Continental HOe gauge layout anyway! My legacy OO stock, track and what-not has been stored away in the loft all of these years. They are thus in reasonable condition though haven't run for probably around 20 years! I am conducting an audit of what i have got, to see what can be reused (to be honest not a great deal though i found a box full of OO/HO scale people!) Its nice to compare the OO gauge to HOe in any case. I may try and sell some of this old stuff...
