I think it's been mentioned on the forum in a couple of older threads, but the RAL brand (i think it stood for Reel/Real Appeal Lures?) is no longer in existence. But as Dmitriy says, the designer (Sam Morrison) still makes lures - as Garage Tackle. Not to be confused with Blaze Garage, which is the new brand of one of the guys behind Hitter lures, I believe.
Check out Facebook under Garage Tackle. But limited numbers.
Ebbtide in Australia is a specialist topwater online store which has Garage Tackle lures when available (not in stock right now). Maybe Rod & Reel in Newmarket?

I grabbed a second hand Haku which came up on the sale forum a couple of months back, and there's been another one since then. Slightly bigger than you're after, though.
One of the gurus like Dmitriy may be able to recommend a very similar swimming stick that you can grab in the meantime.
