I seem to remember reading somewhere that there was no definitive way to
tell if you are looking at a "improved" SW77, only that if you have a "late
model" unit, then it has the improvements.

Okay, so I want one. An SW77, that is. But I can't afford a new one, so
I'm going to be buying used. I understand that there were improvements
made
around 1994, and the new models had serial numbers in the 900,000 or
47,000
range. So far, so good.

But then I read that there were more improvements made in 1997. Can
anyone
tell me what serial numbers identify post-1997 models? Or other
identifying
characteristics?

Thanks,
Sean
