JSowers, re: the chrome switchhook on ETS's red 554 -
I need to defer to ETS on that since it's his, and I was not there when he opened it up and did the cleanup on it. I did read the linked previous discussion, with chrome appearing in 1957. Thanks for that.
ETS would have to tell us this, but I suppose that if the component dates are all late '56, it's possible that it *could* have been assembled in early '57 and thus ended up with that chrome switchhook. All pure speculation on my part. I have no idea whether it has any indications of visiting the WE refurb shop, ETS would have to answer that as well. From what he told me when he got the phone and was working on it, everything appeared untouched original with a 50 year accumulation of dirt, etc.
The switchhook being a "hard part' and not a typical wear item, you'd think that if it had been replaced in its service life, there would be at least one or two other components with non original dates. Or no?
The wood backboard on his phone came with it, originally red and needing a repaint, which he did. Does the OE wood backboard help to date the phone at all?
