Before I found a place to engrave steel properly (or like when the place in L.A. f'ed up 3 panels), I did a few with just a flat Front Panel Express panel. Not perfect as there's a gap when you close it up, but better than nothing. Some were painted, but some were just anodized grey. PDF of that:
Another PDF for a batch of 10 old steel panels to be engraved. Thats probably enough examples for now.
P.S. Doug, I don't remember doing any 1965 serial no. units. Which doesn't mean they aren't mine as memory is sketchy, but the ones you saw might be from another guy who started doing them after I stopped. Dunno?
Last post until something better comes along.
For the guys in North America who want or need good work with real old fashioned pantograph engraving on steel rather than on aluminum, then the company in Canada I used was called Poltec. Yes, Poltec.
I lied. Another quick post.
Found an old picture with Joe Meek and early versions of the RS124 (looks like he's possibly using 5?), these RS124s look like they're without the "Balance" mod so, they'd be without all the stuff in production modification note 2.
It says RGM studio which was his Holloway Road home studio, but that desk is an Abbey Road REDD.37 so it's @ Abbey Road. Maybe around 1962/1963? but I'm not an expert on Meek stuff.
