Hi, I have just purchased an interesting shutter style signalling lamp (no provenance). S. Smith & Sons, VD, series 416, mk II. It is a lot bigger than any signalling lamps that I can find reference on. I can't find any other like it. Can anyone help? Thank you in advance.
Not this type IMHO, looking more stationary. There is no the British Royal Air Ministry stamp and also no Ref. number and the serial on it. Just the Broad arrow. It looks like a lamp from a larger transport, passenger plane or a flying boat. Also an airfield tower is possible too.
OK. the "V Broad Arrow D" logo is damaged. There should be the "W" letter instead of the"V" one. This is the logo of the former War Department and the arrow itself could usually be found nestling just between W and D what stands for War Department. The WD logo does not guarantee or verify that the weapon or system bearing it was ever used in combat, it only authenticates it as government military property. It was used to 1964 when the War Department became the Ministry of Defence
Thanks yes it's more that size. It's quite neat it has a pin on the side (on a chain) that inserted, holds the shutters open turning it into a searchlight. Which might lean toward airfield use...
This appears to be a signal lamp used on the ground to signal to aircraft. It is a variation of the lamps used from WW1 through to WW2. I have seen images of the RAF Mk. II with Series 141 and Series 200 (Images in RAF Museum Collection). Began to be used from at least 1915 by RFC signallers at aerodromes and other locations and also from artillery batteries to signal to aircraft during artillery spotting missions. Used on tripods generally but could be used hand held, some examples of WW1 use (from RAFM images) below:
I hope that is of use.
Yes, however, it should be noted that similar lamps could be used on aircraft, a book on the history of No. 3 Squadron has this image:
Barratt was the commander of the British Air Forces in France during 1940 and then commander of Army Co-operation Command. The use by Barratt of this lamp is mentioned in McCudden's 'Flying Fury' page 53 (this appears to be in November 1914):
By the end of 1916 the RFC wanted to standardise on the Aldis Lamp on aircraft, 6 per squadron. A series of returns during December 1916 indicates the lamps then in use, for example No. 8 Sqn. had 6 RAF (Royal Aircraft Factory), 3 Hucks, 1 Aldis and 4 "A French pattern" lamps. No. 1 Sqn. had 6 Hucks, 3 RAF and 2 "Smith & Son" lamps. The RFC were keen to reduce the size and weight of lamps when carried by aircraft (like much of the equipment in use).
Amazing bit of research thank you for that Mike. You've found it. Much appreciated. Very interesting, I wasn't expecting it to be in use that early. Now to find a similar tripod stand for it...
