Vintage Thomas the train

So I got this from someone who collected Thomas the train and sold it to me in the box. When you open the box, it appears everything is perfect and not used. However, to take pics and to post for sale, I opened it; which admittedly I didn’t do for years. My bad. It was instant system set 1 which I thought was cool. Anyway, some items are missing and some are additions. It’s still a 1995 item! Missing: one sign, Sir Topham Hatt, and the engineer. What’s been added: I believe it’s Brio brand, but a petrol barrel, one cargo car and two “loads” with the holes to fit onto the cargo car. And one random small track piece. So lots of it is collectible, and wood tracks are honestly timeless! The box is weathered but generally in good shape for a toy box from 1995! Happy to answer questions! Would love for this to go to an enthusiast! Thank you!
