is it a structure to support some sort of weather protection

is it the ship that deployed the route marker buoys for d-day?

Bungee strap to provide additional acceleration for unloading.

Mike

A structure to increase the buoyancy with heavy loads?

 

Andy

If the structure is above the vessel... then could it be a docking station for a dirigible?

Are the red lines cable or a solid structure? I've just finished work! :-D

More cable-like than solid Tony.

I'm still about but not with the vaguest of ideas.

 

I the dotted line a structural element of the vessel?

Well it is an additional structure on the vessel & attached to it at certain points. But it is not an essential structural part of the vessel. The vessel was built independent of this structure & it can function perfectly well without it. The red structure was later imposed on it for an additional purpose.

I think I'm going to bed now, but I suppose its the middle of the day for you;)

Fire fighting pipe work with hydrants along the sides in case a tank caught alight.

Richard nope not that, but you have a clear field it seems everyone else has given up/gone to bed.

Dammit, just looked on the previous page, a bloody landing craft, :embarrassed:

Yes Richard we've moved onto what are the things marked in red?

OK, you did not say that it was Not a submarine, so going at something else you said, is it refuelling and fresh water pipes for serving a sub at sea, enabling them to stay out of port and on patrol longer?

Richard its not a submarine or a support vessel for one. Nor directly related to submarine warfare.

I have not been keeping up with this thread so might suggest something already said. It is some sort of sensor or device to hide the object from radar or sonar, of which I think could be a submarine.

Richard nope its not a cloaking device.

Could it be some sort of disguise to disorient an ardent enemy pilot? Clutching at straws really...

It's always worth having a go, but its not that.

This rather modest sketch is from a very detailed research file commissioned in Feb 1941. The implications of it were absolutely crucial on the ability of the Royal Navy to defend the UK. It includes many graphs & calculations, in fact I should really give it to a museum. I say that in case anyone thinks this stuff was just be googled up.

Something with a capstan and pulleys?

 

Andy

Nope its not that Andy. Sorry I realise there are several other dotted lines. The significant ones are the red lines

Clive. Sketch plan of a landing craft! Me thinks. Jerry

Well done Jerry, yes very good! It is indeed a "Tank Landing Craft"

Just remains to work out the purpose of the dotted lines.

Mini Sub

It looks that sort of thing Davey, but this is marine.

Yes that media scale is rather annoying isn't it....

 

So broken lines usually denote some thing hidden or below the level of the continuous lines, dare I suggest a marine or submarine object?

The dotted lines are the real crux of the drawing really & it is marine Bernard.

A BALLOON of sorts

Could be one of those daft shaped ones Wally they come in all shapes & sizes these days. But it's not one of those.

is it made of glass it is it a cross section of a paraffin lamp glass and mantle

I'm in tune with your thoughts there on glassware Wally, but not made of glass as it is big thing. Measurements in a minute.

Some sort of scale would be useful, would it fit in a matchbox or a football HMVF tank playing field?

What system units would you like Bernard? The British standard media scales are: a potato, double-decker bus, olympic swimming pool, premier league football pitch, Wales, South America or the Moon.

At a guess I think its somewhere between the double-decker & the olympic swimming pool. I'll go below, I've got a little diagram & come back with it.

AFTER the last one first thought one of them bottles they give you if you are male and in hospital but is it a type of radio a

valve

Although it looks rather like an open ended one Wally :embarrassed:

Indeed some of those thermionic devices do look rather like this, its not that either

Sketch of a doodle bug engine prototype

A very ingenious suggestion Bernard but its not that.

In case anyone thinks this is some idle doodle (sorry) this a sketch at the end of a report that at one time was classed as secret.

An easy one now:

Changing from the Lucas to the AC Delco distributor is fine. But there is a major problem:

The Lucas distributor uses a pair of identical contact breakers, which are not difficult to obtain.

The AC Delco uses a contact breaker that is the mirror image of the other. One is obtainable but the other is not.

As for sparking plugs if your engine is all tuned up nice & behaving itself & you don't use the choke (I have removed my choke cable) then I run RSN13P but if you find they carbon up & you want the heat to burn it off (because the tip protrudes more) many like to use RSN12Y.

I'm not familiar with using RS5-7R

I think it might be Avis. They were always on the left as you entered the stalls at the Hop Farm, I think there were in a comparable position at the racecourse. It is very much the sort of thing that they sell.
