"Treasure" brought up from shipwrecks on the seabed by scuba divers.
For "Treasure" read - mainly bits of brass rubbish. For "Brought up" read - furiuosly chiseled off against the clock. For "Scuba Divers" read - thieving pikeys.
For "Seabed" read - murkey depths of cold water with visibility of two metres.
For Spidge there is a heirachy of value, disregard all gold, jewells and other fantasy land nonsense the real wreck treasure chart goes something like this:-
1= Ships bell
2= Telegraph / telemotor
3= Compass binnacle
5= Steam whistle
6= Nice brass Nav or deck lights
8= Crockery & cutlery etc
Consolation prizes for the lower ranks of the air diving one tank numpty
Rubber soles from dead seamans shoes, unidentified piece of brass, crockery fragment, lead shot, hooked up fishing weights, pieces of diving equipment dropped by other novices.
All of the quality items have to be reported to the Receiver Of Wreck who finds out if you are allowed to keep the stuff. The remaining detritus is used to decorate your fireplace until you get married when the wife "accidentally" puts it out for the dustman.
"Dived the Lanfrac last weekend"
"Hur hur, find any gold"
"Er, yes actually! a solid bar of it, unfortunately it was a Leigh Bishop
trip so in fact it had been placed there and was lead cast and sprayed gold to look like one"
"Hur hur - Fools Spidge!"
