I also have a Beale Street Blue ES-335 that I love. I am not able to afford to keep near duplicates of various guitars either. I don't know if I would want to sell my 335 for a Freddie King model. But given the chance, I would explore that possibility.
Wanda King is Freddie King's Daughter. She still lives in Dallas area and she performs routinely around town. She has a wonderful personality and loves the association with her famous father. This morning, she posted on Facebook this message: Get the word out and see if we can turn this grassroots movement into a real honorable Freddie King Signature Model. Link: Wanda King - Facebook Link
