look at you bro - what a sweet reel.
that's a Young pattern 1, yes, made in Redditch.
The Japanned enamel finish and latch plate dates it to sometime after 1932 (when Hardy's St. George latch plate patent expired), but before the war.
Here's a history of the founder, JW Young - after 1921, his sons ran things.
http://www.antiquetackleobserver.com/20 ... 1870-1921/During WWII (beginning with 1935 Arms Directive), they made aircraft control systems, and especially firing trigger mechanisms for Hurricane and Spitfire fighters.
They closed the fly reel line in 2001, still bench-make centrepins today, and Jim Young still runs the shop.
The reason so much fishing tackle was manufactured in Redditch was the fish hook manufacturers were first and foremost needlemakers
fishing tackle was just a small sideline for them
Young built his business providing reels to the needlemakers, which through his menu-based wholesale operation, grew into catalog merchants, gunsmiths and tackle shops around UK and the world.

There are two topics at the top of the page, which address cleaning and lube (cleaning) and adjusting run-out on your reel (mechanical bits)
