Mars is a region in the Ardeche...Perhaps the 1st. Mountain Division was in transit for Operation Felix, the invasion of Gibralter which was ultimately cancelled...Ian
It seems to have gas paint on the head lamp but possibly also on the front mudguard. There is at least a colour difference in the position of the front number plate. Horn is mounted at front of frame tube while it usually is mounted at the rear of that tube, strange!
It also has the half circle blackout mask inside! so likely a picture taken shortly after being "conquered".
Probably a 1938 or 1939 machine as it does seem to have the wide toolbox and the double topbolt rear number plate.
Maybe overpainted with KG3 as the toolbox lock has been painted as well!
Still the rubbers on the kick starter crank on the gear change lever.
Rob, it has separate rather than combination handlebar controls which suggest later rather than earlier.
I suspect that the toolbox locks were painted for a while. This detail is from the well-known 1940 images of Cyril Quantrill on what was clearly still a very new C5109 machine (C4101598).
I did see it does not have the combination levers but this could well have been a replacement so I am hesitant to use those as indicator for built dates.
What may be another indicator for a later bike is that it appears not to have a Ni-Fe battery.
Clearly an assumption, based on the fact that I do not see anything in white on the regulator.
Most pictures with Nife regulators clearly show the white marking on a dark background.
Of course no certainty this is the original cap on it but being a fairly "new" bike I assume electrics may not have been tampered with, apart from the Horn!!
BTW on the Nife's, I have made a apparently common mistake. Nife is a brand name but the actual metals used in it were Nickel Cadmium !! I am in the process to amend my initial article on it and sent a correction hopefully to be published by the VMCC.
It's very funny that a company would register nife as a brand name Rob. In the past I have worked with both NiFe cells and NiCad cells. NiFe standing for Nickel Iron.
Typing from memory from our involvement with the guy with the NOS original. These NiFe motorcycle batteries were made under license from the "Swedish" parent company by the British Battery Co for Lucas.
I know it sounds strange but the Lucas C105 "Nife" definitly was a Nickel Cadmium battery and "Nife" was definitly a brand name in this case.
I obtained an article written by Scott Atkinson, the first managing director of the Batteries Limited firm (as it was called in the 30ties) in which he also described the confusion about the name and the metal contents of the battery.
The Jungner company started with the manufacture of NiFe batteries in late 1800 and marketed these under the "Nife" brand name.
They developed the Nickel Cadmium version while making/selling NiFe batteries and retained "Nife" as brand name also for the nickel Cadmium batteries as the brand name was well known in those days.
NiFe as Nickel Iron batteries were and are still made so there is no doubt that you worked with both!
My initial article can be found on my website www.wdnorton.nl but it needs to be corrected for this confusion issue.
Thanks Rob that explains some of my anger in my youth.
The expensive NiFe dry cells I purchased were no better than Nicad's with the same bad habits.
I've read up on Nickel Iron Batteries and it's a shame they seem to be all but lost to history.
It is indeed a bit difficult to find I will change that in future to be more easy.
It is a pdf file to be downloaded, but the link is somewhere in the text and only visible because it is blue.
This should help https://www.wdnorton.nl/Electrical_equipment_page/Article%20Nife%20C105%20issue%202.pdf
But be aware, this still is the old version in which I made the incorrect remark that Lucas C105 Nife was a Nickel Iron battery instead of a Nickel Cadmium battery.
I will send you the correction I wrote for the VMCC by mail.
