Need Help... N.E. Mk 1 WW2 1943 Field Telephones
I recently purchased to Canadian Army Field Telephones dated 1943 at a military show. I am new at this particular item and need a little help with the operation of the unit.
Is anyone familiar with Northern Electric Telephone Set "F" Mk 1 operation? I am looking for a sufficient battery where none are included in both sets? Also, any idea of the value of both which are in working 8 of out 10 cosmetic condition? Thanks David |

Re: Need Help... N.E. Mk 1 WW2 1943 Field Telephones
You should be aware that this is a UK forum and most members are British. Canadian forces did use some British designed telecoms equipment during WW2, usually manufactured locally, but there's no reason to think that this telephone is a UK design and nobody here may have experience with it.
Hope I'm wrong of course Paul |

Given, however, that it is described as "Telephone Set 'F'", it may not be so very different from the British sets with which it shares the name.
As far as batteries are concerned, the British sets use two 1.5V cells in series. Here is a link to a picture of an original, but "D" cells are areasonable substitute. A picture might well be helpful.

Re: Need Help... N.E. Mk 1 WW2 1943 Field Telephones
Based on my understanding, including Canadians forming part of the core of the British Forces during the war upto and including August 1944 when the Canadian 3rd army was constituted, Canadian manufactured field comms were a 'shared' resource.
UK input is generally usefull given the history of our combined shared equipment. Thanks for all your help. Hope I get a manual of sorts for it... Cheers, David Quote:

Re: Need Help... N.E. Mk 1 WW2 1943 Field Telephones
Thank you all for you assistance and reply.
Your British WWII Military Field-Telephone, Type 'F' Mk: II. is essentially similar to the Mk 1 with exception to some design modifications / enhancements. I will be in London in June. Would you have a suggestion where, or a lead to get 2 or 4 of an adequate battery? Cheers, David Cheers, David Z Quote:

Re: Need Help... N.E. Mk 1 WW2 1943 Field Telephones
The original (no. 12) cells are no longer available, but old ones are sometimes available via the likes of eBay. Obviously, the actual cells are unlikely to have any useful charge in them, but they are almost identical to those inside a 996 lantern battery (the 6V battery with spring terminals on top).
If you unscrew the terminals on the no. 12 cell and prise open the flaps at one end of the case - probably the bottom would be best - the cell should slide out of the case. Once the terminals have been removed from the original cell, they can be soldered to the side of the cell extracted from the 996, which can then be reinserted into the cardboard case of the no. 12. Alternatively, there is a member of this forum (located in the USA) who may be willing to make reproduction cases into which a modern "D" cell can be inserted. I'll leave it to him to post if he feels able to offer help. The other option, if you're not worried about the appearance of the cells, is simply to use two "D" cells in series, as I mentioned earlier in this thread. Plastic cases are available for this purpose. As far as value of your sets is concerned, I notice from your picture that you have the wooden cases, which is a good thing, and given that your sets look in quite reasonable condition, I would expect to pay about £15-£20 for one in this country (I'll leave you to convert that into Canadian dollars), but I'm afraid I'm not in the market for them as I already have a number of British ones and the cost would be totally swamped by the cost of shipping such a heavy item across the Atlantic anyway.

Our type 'F' (your instrument also?) was meant for 'back-office' duties, and was effectively a more robust desk instrument, hence the use of a cradle-switch. The type 'D' was a 'battlefield' telephone, and could function in any position. Any chance of a picture of the schematic?

Re: Need Help... N.E. Mk 1 WW2 1943 Field Telephones
Thoughts are that it is indeed a Type 'F', but a Mk 1. Compare with the Mk II, shown below.

Well, I tried to post the pic, but to no avail. Likely I've posted the pic before and am prevented from showing it again, so there's a link here.

The forum software does not allow the same image to be posted more than once. An easy way round this is to crop the image slightly.

Re: Need Help... N.E. Mk 1 WW2 1943 Field Telephones
Excellent tip; many thanks! Not much difference in circuitry - I am guessing that the 'F' Mk.II took advantage of the 'Magneto Generator 26' (Alinco magnet) rather than the 'Generator No:4' which seems to be fitted to the Canadian model. Perhaps a different mic insert as well (in the correct handset, of course!)

Re: Need Help... N.E. Mk 1 WW2 1943 Field Telephones
Apparently; why reinvent the wheel.
I have yet to test both units, but I was told by the seller he has used for over 40 years. Both are in impressive condition. I will likely test once I establish a musuem over the coming years. Thanks for your input Cheers, David |
