Richard I don't know, 223 gets mentioned a number of times in the original German papers. This report is from the Combined Intelligence Objectives Sub-Committee Item No.19 File No. XXIX-54. I'll try & post up some more extracts but upload speeds are very slow this morning.

Chris well done, the ignition was the result of an injection but of what I know not, other than it was "Ignition Oil".

Richard that is a good link to a most impressive bit of engineering. But it doesn't cover the aspects of this particular research I have in front of me, this engine was running off 87 octane petrol. The issue investigated was the novel method of ignition & in the earlier MO it was overcome with a low voltage spark sliding on the porcelain of a special plug.

A lot depends on when in August, as there is lot going on in July & August (not round here mind you) When you know a date & if, as your website suggests, you want multi-period then it might be worth posting on here: http://www.livinghistory.co.uk/index.php

Neither are mentioned Richard.

Wally I don't know if ethanol is part of it but there is no mention of ethanol. The focus of this investigation was on the ignition method (as outlined in MO No.190 high voltages were a problem at high altitudes).

Nope not water Wally.

Yes it has a bearing Nope

Sorry missed you there Pekka, not multifuel as we know it but there is something in what you say.

No not that Tony

Not a turbocharger Richard, does this help?

Not this particular investigation Wally.

This particular investigation was not focussed on piston failure, but another issue as "engine outputs were boosted and higher altitudes encountered".

Ah sorry, this is from a 1945 intelligence report of what was discovered at the Junkers plant in Dessau. It states the single cylinder tests were carried out in December 1944.

Richard I can't see the test sheet.

Good thought Pekka but not that.

Not that high up Wally.

Yes Wally, this was what it was all about. It was an attempt to achieve that by a particular means.

Good bit of googling & although based on Jumo 223 this experiment was on a 1-cylinder engine!

Well as there is no Dad's Army this Saturday, here is a little teaser. These are the results of German research in WW2, something that the Allies apparently knew nothing about. I have googled various bits of the answer & there seems to be nothing about this wartime research out in the internet.

Yes you are right, I have that book as well, it is silly mistake as the original promotional literature some 3 years earlier was using the name Shorland. It is strange as RE Smith was a most knowledgeable writer & a prolific photographer of the 1960s-70s at arms shows & official events leaving a valuable photographic legacy of British Army vehicles that were in service, about to go into service or didn't quite make it into service. I always delight in seeing his photos illustrating vehicles of the time in their intended roles.

This is what I ordered on 2mm brass

I've bought brass plates from them. Not cheap but high quality & good co-operation in getting what I needed.

Yes on the floor & on the seats. This 1971 RAC publication is the only place I can see any reference to using this protection. There are pictures around of stripped down SWB Land Rovers in NI with sandbags on the floor, but not actually on the seats. NITAT literature & the Land Operations series make no mention of the practice. Although stripped down Land Rovers are suggested for ease of disembarking, good visibility although the vulnerability had the effect of keeping the crew alert. Land Operations - Counter Revolutionary Operations were based mainly on experiences from Aden & Palestine, there were issued in 1969 & updated in 1970 & 1973 for NI. Not well proof read as for example we have a Shorland called a Shortland captioning a picture of a Mk 1 Pig & the "Shortland" is then illustrated with a picture of a Pig.

Richard I have a number of development & technical documents for SWD Stages 1 & 2. It is mentioned briefly here: http://hmvf.co.uk/forumvb/showthread.php?17955-Non-Lethal-Conflict
