Cross referencing obscure shotgun part #s

[Guest Average Joe]

I have a Westernfield Model 25XNH-402A I am working on, needs a new firing pin.

The Westernfield I have I believe is the same as a Noble Model 40, I have found a firing pin - https://www.gunparts...290A&catid=8872. My concern is that this parts supplier also has the Westernfield model listed also but no firing pin listed for it, I am sure they are smart enough to know what parts cross reference to others which makes me think they may be different.

I am hoping that maybe someone here with more experience than myself will either just have this knowledge rattling around up there or have some reference material that can either confirm or deny the cross reference. Then of coarse if it don't cross reference can anyone advise me where I can find one.

Thanks in advance,

Joe
