Lauren Child Posted January 30, 2016 Share Posted January 30, 2016 I've seen a wartime /period photo of one on the L/H side of a QL too but didn't like to mention it :embarrassed: cheers. Is it the one with 3 or 4 QL's lined up? I'm wondering if we've seen the same photo or different ones, indicating potential wider use.

Adrian Barrell Posted January 30, 2016 Share Posted January 30, 2016 The DP version is shown in both Comet and Cromwell workshop manuals, 1947 /48. Yes Lauren, that's the earliest mention I can find of it too. All my 1945 and 46 manuals show the normal H1 type. Quote Link to comment Share on other sites More sharing options...
David B. Posted January 30, 2016 Share Posted January 30, 2016 I wonder whether looking at parts lists which are often specific to a particular contract would give you a better idea of a changed or superceded item. Manuals or handbooks sometimes carried illustrations or plates which showed out of date items. Is it the QL drivers handbook which carried a picture of the larger early type headlight in quite late wartime editions ? Quote Link to comment Share on other sites More sharing options...

Hi David, This is gleaned from a QL parts book dated after production ceased, and gives cut-in's for part changes, by chassis number. Using info from Bart Vanderveen I can deduce the following; B/WD/H1 Chassis no. 4795 (built 1941) to 44966 (early 1945) B/WD/H1/DP Chassis no. 44967 (early 1945) to 52122 (1945) B/WD/H1/0 Chassis no. 52123 (1945) > The last chassis built was 53247, in 1945. cheers Richard Quote Link to comment Share on other sites More sharing options...

I'll have look at my Austin parts books. What was the B/WD/H1/0 ? Cheers, David. Quote Link to comment Share on other sites More sharing options...
79x100 Posted January 30, 2016 Share Posted January 30, 2016 No confirmation of the manufacture of new headlamps but various sources refer to the reduction of black-out regulations from September 1944 onwards. Field modifications were made to take this into account. This extract is from the official 'Adminsitrative History of 21st Army Group :- "Speed of manufacture was in many cases greater in BELGIUM than in ENGLAND where any new project had to be placed on a priority list. For instance, at the end of September it was decided that in view of our air superiority an increased amount of light could be used by vehicles at night in the rear areas. It was therefore necessary to design a method by which vehicles could use more light in the rear areas but could conform to operational requirements when in the forward areas. 200,000 headlamp modification sets, each consisting of sixteen different items, were designed and supplied within four weeks, whereas a minimum of three months for the task had been estimated by the Ministry of Supply in UK".

That would explain it not showing up in the armoured vehicle parts lists until the MoS caught up. Quote Link to comment Share on other sites More sharing options...

Lauren Child Posted January 30, 2016 Share Posted January 30, 2016 (edited) By way of completeness, this is the DT version. The glass is completely flat and can be swapped with IR blackout glass (painted film on the inside). The raised edge has a clip that can take a diffusion mask for use with the Tabby IR kit, giving a wider beam.

David B. Posted January 30, 2016 Share Posted January 30, 2016 Just found L-WD-H1-DP listed in January 1945 K2 Ambulance Parts List, Chassis no 74701 onwards. Earliest yet ? Quote Link to comment Share on other sites More sharing options...

Ian L Posted January 31, 2016 Author Share Posted January 31, 2016 3 hours to go & now over £146, I was picking up new boxed one's for less than £50 just 2 years ago & second hand for less than £20 :wow: http://www.ebay.co.uk/itm/262252291071?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Quote Link to comment Share on other sites More sharing options...
Lauren Child Posted January 31, 2016 Share Posted January 31, 2016 As ever with ebay, if items go for super high prices it doesnt really mean that they're intrinisically worth that much, just that they're worth that much to two individuals who need that part to complete a project. £150 for a light sounds a lot, but chancing a bid at £150 to finish off a £10k truck is probably worth the risk of it going that high, even if it's overpriced for the component.

Lauren Child Posted January 31, 2016 Share Posted January 31, 2016 (edited) Thanks for that, Lauren, I've got a pair of these in store and I didn't know what they were. I dont suppose they've got the blackout glass, mask and clip with them? The Tabby manual(s) that Clive has got show the IR lights as an extra set of lights complimenting the originals, hence thinking about the photograph that Ian and I have seen with the extra lamp of a different type on the QL.

Ain't that the truth! Witness the Loyd carrier workshop manual that finished last night at £260 versus an identical one that finished Friday night at £26! What is the 'value' of one of those?

fv1609 Posted February 1, 2016 Share Posted February 1, 2016 It all comes down to who sees the auction Yes sometimes a seller describes something ineptly or incorrectly or spells it incorrectly. Consequently there is little in the way of bidding & you can get a bargain. Sometimes a well meaning person not interested in the item spots it & as a public service draws everyone's attention to it, that can be great, but not so great if you are patiently waiting for the sale to end & you have placed a low bid.

Deadly Posted March 20, 2022 Share Posted March 20, 2022 Back from the dead ... I also found some B-WD-H1 ( Shell) and ring is stamped B-WD-H0. These are unused but maybe wet at some point all light have rust. They don't have bulbs inside, any of them. Can anyone help me what these were used for ?
