The HP VFD displays of the 90's where of a green tint, but it seems the more recent VFD's have a more blue tint. Was there a change in the display color at some point or is this just a camera color balance thing?

When the VFD's gets older, they are drifting in to the green color direction.
Also, a new VFD is brighter and appears to be more blue on the new windows.

Thanks HV, my new to me 53132A arrived today and the display is bright and bluish. I lucked out and it also has the later firmware which includes the ',' to separate the groups of three digits.

In the eBay ad photos, it looked a bit rough and the display was questionable.
Amazing what some careful cleaning will do;
