Without going into the gory detail, I can tell you from personal
experience that it's difficult or impossible to get an acceptible
silver plated surface without the use of cyanide based chemicals.

That's pretty much what I thought. I need the best plating I can get - it's
for the insides of the LOX pump in a small rocket engine turbopump. Any
hints?

You should be able to purchase the materials that you need from any
electroplating supply firm, even in the UK, although as here in the US
they may be unwilling to sell to individuals due to liability
considerations.

For years we in the UK used to have to sign the poisons register to buy
cyanides, and you might have to get someone like a doctor or a policeman or
your local MP to vouch for you if the seller didn't know you personally -
pretty reasonable, and no direct seller liability problems (we don't in
general have those here anyway, or at least not as bad as the US does).

I don't know if that's still true though, what with the HORRegulators,
starring Nanny Blair and the Auntie-Terrorists.
