Recently acquired a Shaver post ponder serial number 4844. With talking to Shaver Mfg. narrowed it down to being manufactured in 1969. Also learned that with the Gresen valves used back then, it required changing out the valve to switch between open and closed center. Not just switching plugs.
Anybody have experience with this era pounders in regards to valve numbers used and/or have a owners manual they would consider scanning from this time frame.
Thank you
