Thank you for the reply and to anyone considering my note above.
I did manage to get my question answered in another forum. So I was able to get my bolt apart and back together again - but it was still a PIA.
This YouTube video shows how to get the charging handle off bolt of a very similar action - it turns out that the charging handle is what keeps the firing pin assembly inside the bolt.
