Those look like 300, 400 or 500LX STI's Steve.
I have a 200GS front shifter you can have for the price of postage.
By the power of pressed steel and plastic, the shifter and brake lever aren't actually attached to each other and can easily be separated. I have the brake lever as well if you want that too though.
Couple of quid should cover the postage.
PM me.
