[RE-wrenches] Context XW+ Random Factory Defaults

[Jason Szumlanski]

Are they open on Saturdays? It doesn't really matter anyway because I went
out to the remote island on an emergency basis this morning, and we have a
big storm rolling in, so we had to hightail it out of there. I wouldn't
have had time to call.

I definitely intend to get in touch with them for any advice they might
have. I was hoping to get some clues from anyone with similar experiences.
