I've never heard of the LS-4 B model... We have an LS-4.. not for

Good luck finding one as I think there is only two in the whole
country.

We had 2 privately owned 4b's at GBSC. One was destroyed in an
unfortunate accident (pilot recovered fully) about a year and a half
ago. The owner of the remaining 4b says that he's been offered more
money for his used ship than what he paid for it (new) - presumably due
to the weak US dollar. A sweet glider.
