1975 Entex LOC BLOC SET, 850 pieces- Lego type building set

This set originally came with 850 pieces but not sure how complete it is now- the box is pretty full so it could be complete. Includes gears and axles. Parts all look clean and in good shape, box shows wear.

Send your zip code for ship cost- should be between $6.99 and $12.99 if you are in the continental USA (April 2013).
