Circuit
Top view. Tubes: UX171, CeCo Type A, UX201A, 401A, CeCo Type A. The radio probably owes its name to the W-shaped line-up of the tubes and the knobs on the front panel. The UX171, first made in 1926, must be a later addition. This tube gives more amplification then a standard 01 tube. The CeCo Type A is almost identical to a 01 tube.
Bottom view. The speaker driver was missing.

The loudspeaker
A fitting driver was found: a Western Electric 523W.
Control label and type plate. The radio was last repaired on May 3rd, 1929.
This is proof that the radio was probably made by Wilcox Laboratories: the type plate of the Lansing W (above) is almost identical to that of a Cathedral Junior. (Picture by Radiola Guy)
