ferramatori su FIMF

I recently purchased a Rivarossi 0389 BR 61 001 which came with no literature and only one each of two different couplers. I am looking for a source for the locomotive breakdown that can be shared and a source for the odd couplers which work with a vertical NEM pocket.

do you mean this?

Yes, but I had found it poking around after posting the request. Still looking for a source for the couplers or hooks. Thank you.
