The clam is a Mine/demolition charge which is attatched to the target by strong magnets.It contained 8oz of HE.IT could penetrate 25mm of plate metal and was capable of cracking engine blocks,and bending rail track.The Mk1 was made of tinned steel,The Mk2 and Mk3 were made of bakelite.A "L" delay was used to detonate this device
This image shows the clam as found

Jean Paul
 
a good question ..i dont know if they used the same L Delay ,i would think its a good chance they did ,if we supply the charge why not send with the Switches,,,,,,,, anyone else help here ??
 
Can someone explain the significance of the green and yellow stripes? I understand the 55/45 indicates the ratio of TNT to CE and assume that the stripes also have something to do with the type of filling. Does anyone have a reference that explains this?
 
Hello, clam-owners

just having missed to acquire a type II or III clam :tinysmile_cry_t4: I wonder how much such a piece in reasonable condition could be worth?

Limpets

Notwithstanding the special limpets made for specific operations there were three generations of limpets in British service:

1. MD1 designed circular limpets. Four marks developed during WW2. The image shows a Mark II.

2. ES6 designed rectangular limpets. Initial design with ten magnets but mostly seen with six. Two marks produced and another on the drawing board by the end of the war. The image shows a Mark I.

3. ES6 designed limpets for the Sleeping Beauty Programme (motorised submersible canoe). Standardised rectangular charge container with various configurations produced by the use of harnesses. The image shows the Buoyant limpet.

Hope it is of interest when you are rock pooling for limpets.

WoW Bonnex,

Thanks for posting! I had only seen the ES6 in the middle before today.

Thanks Hazord,

You had your own version of the 'Rigid Limpet' as the ES6 rectangular was sometimes referred to. The US (OSS) version had a charge container made in plastic. Some were sent over here but plastic had already been ruled out in the design of the limpet because it was not compatible with the explosive fillings used over here.

OK, but look in the middle of the green, there is a number three - what does that mean?
 
Code 3

Jeff,
The code on a band like this is usually to do with the filling composition, standard of TNT or RDX etc., used in the mix for instance. I have 3 recorded as PE but I will do a bit of homework to see if I can find a definitive answer.
