We started with about 130 of these and have rebuilt and restored many over the last couple years. We have 30 remaining and can restore with the model A face, several early ford fantasy faces, and also can do special make autos. U S gauge made at least 25 different faces, as we have that many in our collection.
It does take special tools to open and close a case without damaging or scratching it. Glad to do that for free , but with postage at $5 minimum each trip it gets expensive.
