Conversion to GBP 

I have removed the following text because I not only cant find anything to back it up, but also because I am aware of specific instructions to the contrary:

The Falkland pound has always been equivalent to the Pound sterling.

Reasoning:
 OANDA specifically quote a FKP/GBP rate which differs over time
 I work for a UK clearing bank, and we are certainly aware of the procedure - daily exchange rates for FKP are sent to us
