Hi. New member here and glad to be with you gentleman. Need help to id several tubes.
The first 2 pics are of a Daven MU-6. Note the shape of the globe and color of the Shaw base and the color of the ink id marks.

Notice this tube has a similar colored Shaw base and ink id marks but a different shaped globe.
I believe they are both Daven products but there are not enough id marks to be positive. Can anyone confirm that the second set of pics shows a Daven product?
This third tube is very similar to a RCA WD-12 but etched on the the glass near thew base is the id mark 117A. Very hard to see on the pic but it is there just above the base to the left of center in pic 1a. Glass on this tube is shorter than the WD-12. Unlike the WD-12, however, this tube was made using a hard getter. Any help here?

This fourth tube appears to be a Moorhead product by the looks of the internal structure but there are slight differences. Some id marks on base but not enough. Can anyone id this tube?
