That was the  Viewstar version Tree, the one built in Canada after
Hammond sold it.

B&W completely redid the RF deck before selling under their name. The
only early B&W problem was some parasitics but that was changed by Serial
# 12. I had # 006 and 008 here for long term evaluation and debug. 

They also reworked many Viewstars for owners.

Old  #006 won the CQ CW 160M Contest for me (KQ2M op) in 1987 or 88 as
well as numerous other contests 1987-89. 

If you have anything written up I would appreciate a copy for my records.
