OK, thanks! I'll drop the _SER prefixes then.

We're generally only accepting self-made photos with an open-ish license
(public domain or CC-BY-SA) in the wiki, so using photos from elsewhere
is usually not possible. We can ask the author of the eevblog.com
photos though, sure. Thanks for the pointer!

If you want to make a wiki page for the BM-257s and/or if you can do external
photos (without opening the DMM) now or later please do let us know anyway
and we'll make a wiki account for you (or you can just send the photos to
me via email if you prefer that, I can upload them).


Cheers, Uwe.
