This is the introduction of the combined Silver Streak/Ye Olde Huff & Puff cars. On our undecorated car, we are offering all of the old Silver Streak/Huff & Puff parts, but with plain scribed siding. If you wish to letter this for your own road or prefer scribed siding, you can buy any of the lettering from this series of kits separately. Because of the sheer number of kits, we will be renumbering all of our kit lines eventually. Thank you for your patronage.
