Marconi model 107
HI All
I came across this Marconi and tried to find some info on it. From what I have found out is not much, I would like to find out the year it was made. My understanding is that the manufacture date can in some cases be determined by the serial number and this radio has the model and serial number all in one "107.431503". I also read that the Canadian Marconi Company ceased production in 1943 due to the war so I don't think the 43 would be the year, leaving 03 as the manufacture date.
My search of the net on this model turned up nothing so if anyone can help me out in some way I would appreciate it.

That looks like a late 30's set. One of the IF transformers had been replaced with a modern miniaature one. See the conversion bracket?
Very interesting set to me.

Not quite sure what you are referring to, I do notice that the Hammond transformer had to have been added at sometime. In the second picture the gray wires on the right would connect to the batteries (see added photo) and the brown wires on the left appear to have been added as the routing seems to go through a drilled hole and protection (black cloth electrical tape) added to prevent damage to the wire, the transformer also looks like the holes were drilled to accomadate the mounting of the transformer. It's these modifactions that makes me think the 03 in the serial number indicates a manufacture date.

Also there is two other labels stapled to the inside of the cabinet where the red one has a date of 1932 printed on it. These labels seems to have been added at another time from the schematic, I say this because the staples holding the labels in place differ (hard to tell from the pictures, but the schematic staples are slightly thicker and wider than the other two labels)

Re: Marconi model 107
I'm also wondering if I should get the cabinet restored or is it best to leave as is?
If anything I would like to get the glass replaced on the dial as it is completly gone. If that is even possible.

Re: Marconi model 107
1932 isn't the right date. I believe from the tubes it's more likely about 1937.
The transformer you are talking about I believe is the small metal can? That's the replacement.
Other may be original.
I hope they put the correct matching frequency transformer in...
Possibly, battery acid dammaged original one.
If case finnish is bad, I would say a decent refinnishing wouldn't hurt.

Re: Marconi model 107
Does it have any lable that says patented 19xx-19yy.If so i would think that it is safe to say that year 19yy is the year of production.That's how it is with all 3 of my Marconi's.BTW great radio!

Re: Marconi model 107
Based on that i would think that the year of production was 1937 but that's just me.You could also narrow it down based on the tube line up.piratesrevenge wrote:Nick666 wrote:Does it have any lable that says patented 19xx-19yy.If so i would think that it is safe to say that year 19yy is the year of production.That's how it is with all 3 of my Marconi's.BTW great radio!

Re: Marconi model 107
I have a couple of Marconi's that needed dial glass repairs. With the chassis out I made a template with thick poster paper and went to the local glass place that makes custom glass windows and such. He took the template and ground a oval piece that fit in perfectly. It is an idea!
