Have one now which I purchased new in the late 1970s, made by the National Mt. Airy furniture company in Mt. Airy, NC. Couldn’t use it as a computer desk during the years of big, heavy CRT monitors, but it has been my computer desk since I got my first flat panel monitor.
It’s a full size roll top, but has more slots than small drawers which I think is more practical these days. Like most furniture manufacturers in the US, National Mt. Airy is no longer there. It burned down sometime in the 1980s and was not rebuilt.
I have a rolltop from Natl Mt. Airy — bought by my dad in the 70’s I think. It has a matching hutch on top of it, with another rolltop (tambour) in it. It was called the Presidential model, cost around $5k and weighs about 700lb.
It’s 6ft 6in high. And 5ft wide. I could fit inside my rolltop...given a good reason. If I couldn’t get out, it came with a built-in phone jack and a lamp.
I’ve seen the Presidential on ebay (I’m a sucker for antique furniture). Some with hutch, some not. Google it, it’s really stunning.
