The glowing beam tuning indication on my 37-670 is too wide and does not appear well focused.  The bulb is a #55 (7 volts, 0.41 amp) and I do not know if it is the correct bulb. The projected image on the dial appears too wide and not well focused.  The image is also slanted to the left. I have not yet tried to adjust the projector lamp "funnel" in fear of breaking something after a very difficult restoration.  It is not exactly centered and straight ahead.  Moving the projector funnel forward and backward (only a small adjustment is possible) does not seem to matter.  Anybody have any suggestions of perhaps a photo of the mechanism from behind of a correctly working mechanism?  Thanks!
