Allwave 23 variations

[Thomas Day]

I have been reading through the Scott News pages on the website posted here earlier. The first one from 1935 gives the details of the new Allwave 23, and lists a different line up of tubes than the model I have. and only 22 tubes instead of 23. Any idea how long this first model was in production and when the tube lineup was changed? The chassis photos look just like the ones in Marvin Hobbs book.
