Phone Calls Were EXPENSIVE
I remember "KELLER" sending type written notes, always with news from the North West USA. He usually talked about the "FANTON" (Jerry Walin).
My brother's KR "A" in our show room has a Keller "TORQUE TUBE" (Mid section), All my three KG-4's had Keller thottle attachments.
We used Keller "KICK OUTS" but my dad machined "PIPES" to slip over the kick out pin that were much smaller in creating angles....from 1/8 diameter to 1/2 diameter, not to mention my dad made "THRUST BLOCKS" WITH A SCREW ADAPTER, MUCH LIKE BTM ADJUSTABLE BLOCKS TODAY.
