Here is a vintage Tyco part for your vintage HO scale slot cars. This is a mint in the package #6494 pick up for the obstacle car. Looks like three come to a package. This package is unopened and shows a little bit of wear. I believe this is the 1970s packaging for this item.
This lot and the other cars and parts we have up, came from the estate of a hobby store that has been closed since the 1970's.
