[Hammarlund] CQ Robert Fowle / HQ-180 Hammarlund Fixed Freq Assembly

[SX-25]

Does anyone know the whereabouts of Robert Fowle and/or "Amateur Radio Surplus" that once operated out of southern Michigan? I believe he also was known as the "Hammarlund Historian" but that website has been taken over by someone else. I am looking to find a after-market kit Hammarlund offered that I understand he once had in stock and sold not too long ago. It replaced the clock on an HQ-180 with a crystal selector and socket network. If anyone knows of a HAMMARLUND FIXED FREQUENCY CRYSTAL OSCILLATOR ASSEMBLY (Hammarlund part No. 9211-00-00002) I would be grateful for the information.
