The PHILCO Phorum

I bought a small quantity of station tabs and am wondering what they fit?
Pretty sure the one on the right is for the 1937-38 automatic tuning sets
the other two I'm not sure.

All three look like they are for the 1937-38 Automatic Tuning models.

The one in the middle looks like its lower end was broken off.

The one on the right is the early 1937 version. Philco switched to the version on the left during the 1937 season, and this style remained through the 1938 season.

Tnx Much!
