This is what I have been able to tell:
1.FS/WCH
2.Same design, with WCH logo
3.slightly different casting
4/5. Total redesign
6. This

That should be the 6th variation of their 12" lightheaded.

I sent in a lot of pages from California, and I still need to submit a couple more.

Here's a pair at NWS Concord https://www.google.com/maps/@38.0208899 ... mNBLw!2e0/

Wasn't the Roseville one on the site?

That's a weird location to find a teardrop bell. The cantilever is at least 20 years newer than the bell.

Many, many crossings. I can list as least 15+ off the top of my head.

I don't think they'll be any in the Dallas area, since mini bells are mainly found in the north and northeast Rogions on the US.

They have been in the SFO-JFK route for quite some time now, I'd say for more than half a year. They are the usual aircraft that do the route and they replaced the 767-200.

Thanks, it's at SFO.
