Help Identifying this Hiawatha frame.

[Ed Stately]

Found this frame with a 6in thick tree growing between the rear wheel and chain stay. The wheel took most of the damage, but frame is bowed in the back but not bad. Mainly want to know what year and model. Serial number:
WG-24-6100415.1. any info or a place to start looking would be great. Thanks in advance.

The dropouts and "WG" ID it as a Murray frame made for Gambles. The BMA 6 decal on the seat tube shows it to be 1971 or later.
