I see what you all mean now never really noticed it myself, there was nothing under the plastic container at all, it was on a work top in the work shop

Only if the context and location in which it was found was recorded. Otherwise most of the 'history' has been lost.



Gary, do you know where it was found? Should be able to ID the unit if so.

Simon,
yes i do have a location, it was found in between the 2 villages underlined in the photo below, which i understand to be a TK area

[Gary Wood]

Gary, you did a great job. Did you use phosphoric acid?

Matt,
no i used hydrofluoric acid but only a 6% mix, I buy it pre mixed, it is reusable but its not cheap the 500ml mix is £30.00,
cheers

here are a couple of other pennants/signs ground dug that i have obtained over the years

Uh...Yeah. Now I'm really freaked out

Gary-
Those are some incredible ground dug signs you have there. What do you to to preserve them once they are removed from the acid bath? I would imagine that they need to be kept in a very dry, controlled environment?

That SS (poss. TK) FlaK sign is just

Rob,
yes the metal needs to be treated once it is removed from the acid bath, first you need to soak it in distilled water, then dried off then sealed, wax or varnish, the acid removes the rust and leaves the metal fresh this would start to rust within hours, the acid does not remove the paint yet it will remove glaze from porcelain cups as i found out while dipping some m24 stick grenade heads.

someone also e-mailed me asking if electorates would work yes this removes rust but it would also remove the paint as well so if you want to save the paint then do not use that method
cheers

PS before anyone tries this its best to test a painted area as some of the mix's that contain hydrofluoric acid will remove paint, anyone in the UK you need "Cleaner R", try a dry cleaners as they use it for removing rust stains/blood from cloths

Symptoms of skin exposure to dilute HF are not felt immediately, but exposure of less than 10% of the body to it can be fatal, even with immediate medical treatment. Highly concentrated solutions may lead to acute hypocalcemia, followed by heart attack and death, and will usually be fatal in as little as 2% body exposure (about the size of the sole of the foot). This substance is extremely toxic and has the capacity to kill upon exposure rather than simply damage skin and eyes. It should be handled with extreme care, beyond what is given to hydrochloric, sulfuric, or other mineral acids.

Gary- be careful with that stuff.

[Gary Wood]

is not a good choice Gary, I would advise others not to use it

Edit thanks wiki

matt,
yes it is dangerous acid and proper precautions need to be taken with anything like this, higher the % of acid the more dangerous it is, and like anything that is dangerous it can be fatal, but it works well with removing rust, but if in doubt do not try it,
