Size and code

This is a great image! I'd like to put a size indicator in the caption of this photograph. The tube is labeled GN-4. The closest thing I've found is IN-4, which is about 17 mm in diameter; see Dieter's Nixie World. Is that correct? Cheers, Easchiff (talk) 00:39, 29 November 2010 (UTC)

My earlier note seems premature; I found ITT / STC: Numerical Indicator Tubes, which lists the numerals as 0.6 inches (16 mm) tall. Easchiff (talk) 00:55, 29 November 2010 (UTC)
