The Aeriola Senior, a single tube regenerative receiver was introduced in Dec. 1921. It sold for $65.00 including the "WD-11" vacuum tube. The early version had a painted wood panel with silver plated dials, the case was made of Poplar . A later version (early 1923) had a molded Bakelite panel and a Mahogany case. It was later dubbed the "Radiola Senior" & given a metal nameplate to replace the paper "lid label".

Other than the Bakelite panel, the only other difference between the early & late versions is the depth of the "tube well". The "well" is shallower on the later model and the lid will not close if you install the earlier (large bulb, brass base tipped) version of the WD-11 tube. Likewise, if you install the later (smaller) version of the WD-11 in the early model, you will have a real challenge getting it out.
