Mystery 1930s Radio head HELP!

[grhouse]

I've been able to narrow the information down on this radio head to probably the early 30s and probably column mounted based on information from a well know classic radio person. He was not able to help pinpoint the year or manufacturer of the head. The numbering appear to almost be hand lettered and notice that there are only lines at each number and none between numbers as you usually see. Also note that there are no zeros used. The cables are just at 24" long and the wires about 13" long. The numbering is vertical rather than the horizontal that you'd normally see in a dash mounted radio head. We initially thought that this may be an armrest head used in a Limo but the cables are not long enough for that. There is a number on the dial face where the ends are stapled together: 56734. Finally, the knobs that are on it, almost certainly, are not original and should not be considered in you evaluation.

Thanks in advance for any thoughts and comments.
