click pawl mechanism

hi everyone, apologies in advance as i don't know much about fly
fishing BUT I think someone here may be able to help me.

We're making a product for a marine application, it consists of a short
rod and a reel which will be very close in style to a very simple fly
reel (a cross between this and a scuba reel). We're just pricing
stainless plates for the reels, and the next thing to source are the
click pawl assemblies.

can anyone recommend a place we could check out for just the click pawl
bits? quality needs to be pretty good on them

Thanks very much for any assistance!

ps we are in australia but at this point will consider anything
