MEGA Vintage Lot of British Train Cars from eBay - How Will They Roll?

Last year I purchased a huge lot of British locomotives from eBay and have since been restoring them however I don't have much in the way of rolling stock for them to pull so I've been on the lookout for some.
I stumbled across this massive lot of over 45 different pieces of rolling stock on eBay and had my heart set on winning the auction. I placed a solid bid and it worked out.
Today I finally get to open the box and see what exactly I purchased.
