GMorrison
Second, there's no such thing as a glass nose, and I have no idea where GWH got the idea. There was a fiberglass nose, but thats a different animal. It was painted, either o/d or black. Some of the photos of the prototypes with the sun behind them make it look translucent, but it wasn't. I'm pretty sure the 25502 had a black nose, on an o/d aircraft, but that could easily change.
I wish I could find it. I have a reference book on the P-61 I bought when I built the Revell kit a few years ago. I could swear there was at least one pic of a P-61 with a sort of frosted plexiglass nose. Or maybe it was heavily weathered so as to appear fogged and crazed. In any case, the radar unit inside was fairly visible still. Maybe we've seen the same picture.
Edit: Here it is---

That article says it WAS clear when it was still stateside, then painted over for security purposes when it went into combat. Is that what you meant, GMorrison (sorry, I forgot your first name) I'm guessing GWH probably saw this picture. It's the only pic of a transparent nose I can find online.
If you wanted to model a bird that hadn't seen combat yet, you could still do the transparent nose. I think it's kinda cool.
Not trying to be argumentative. Just adding to the commentary.
