.410 shotgun maintenance

[Oldgunner]

I just became the owner of a .410 gage shotgun and it is in need of some serious cleaning. the bore (barrel) was a cinch but I need to get in under the ejector. can any one tell me how to get this weapon apart? It is a Harrington & Richardson BayPlate, ser A190479 Top of barrell say's made in USA 410 GA Choke. are there any books available on thsi? Thanks all.

Here's a link to a schematic of a H&R single barrel shotgun. It may help. They are not meant to come apart like a SXS ort an O/U will. It is much more of a task to drive out the hinge pin, etc.
