Since original spares are not always available and my replacement stock is low I’d be game for fp and extractor. PM details please.

Firing pin's won't be available till later this year, most likely november/december. I'll post more when we are closer. Extractors may either happen this fall, or early 2026, it depends on a couple of other projects/products that use the same 5160 spring steel. If they will mix into the production schedule with our other parts, I will post here.
Everyone, myself included, hates pre-sales, but for a our tiny business, we have to cash flow projects, and pre-sales help move the project along.
Just so people know, I bought an SSD handle and the shank was a different diameter (larger) than the one on my original Haenel. Parts assemblies may be same size as originals but that doesn't mean all of the small bits are dimensioned the same.
Making any replacement parts for honestly any German gun can be challenging. The greatest German propaganda success is related to their manufacturing "perfection". Some of it can be challenging as Germany was just implementing DIN and ISO standards, which don't always align with modern standards. Sometimes you don't know what you don't know. Sometimes the parts don't match the drawings. Sometimes the parts don't match the parts. Sometimes the original parts were made wrong.
By the way, I really appreciate your photo comparison thread. I've used it several times looking at parts. I unfortunately don't own a MP44, so it can be a little troublesome.
Edited to add: in regards to the extractor, we could make them from 4140, that would be cheaper, easier, faster, and it really does not need to be made from 5160. The originals were essentially 1018 with a thin medium hard case. We can do that too. I have a habit of making things so that I never need to make another one. Not particularly a good business model.
