I’ve got more then half that in my parts procurement
I also bid on one a year or two ago, and my highest bid was
$400 and someone bought it out from under me : ) I thought
$400 was a little high myself, but if I had the chance would do
it again, some of the parts are almost un-obtainum : )
Even if you plan on building your own, taking that one apart
would fill your junk box with most of the exact parts you’d
probably want for your build. Even tho I do now have most
of my parts for my build, i would still right out that check…
(I have a stretch account) : ) No money in there, but the
rubber check would be covered : )
Just food for thought, my wife would not like it, but she
understands the NNNEEEEEDDD : )
73 fer now

It had the Eddystone dial, the metal work was excellent and the seller said it worker very well, and was quite selective. He was the second owner, the guy who he got it from was a w4 who had built 3 of the HBR's, including the HBR-18. He was asking $300 for it, and had coils for 80 and 40. Coulda, shoulda, woulda bought it, but $300 is a lot of walking around money, and I' d like to build my own someday. Reason for selling was that he had intended to redo the front panel to improve cosmetics , but it was a project he just wasn't getting to. Maybe he sold it, maybe it will be there next time, $300 might have been more than the " non converted" would be willing to pay.
