I already tried making a font in my previous post; looks like the 5 is almost the same without the serif at the top, but that should be easy to fix.
That's very close, thanks. But does need fine tuning. several of the digits are too wide, and the 5 doesn't match the correct 5 from the gauge image TwoFlower found. I think I can fix it up myself.
My current photoshop file is here:
http://everist.org/pics/gauge/gauge_overlay_7.psd 10MB Photoshop 5.5
That includes layers with the complete 0-9 sample font (incl extracts from TwoFlower's image) plus a scaled 0-9 of your GAUGE font. You can pan that layer to overlay the font digits on their images, to see the differences.
This photoshop version is just a temp version, experimenting. I had scanned the gauge face at 400 dpi, but for dimensionally accurate printing I'll produce an output file at 300 dpi (and matching the printer's true printable area.) So the working file will be a small integer multiple of 300 dpi.
Turns out the gauge gradations are NOT equal. I'd suspected they wouldn't be, since the mechanism has at least two non-linearities I can think of.
As a result, creating fill-in markers in the missing section of the gauge scale is a bit of a fudge.
The dial circle marking isn't even quite a true circle. I have no idea what the manufacturing process was, and whether that was deliberate or an artifact. The actual metal dial plate isn't quite round either.

That's a beautiful gauge. Beats anything I ever found. The glass is bevelled! I also notice it does not have a blow-out plate on the rear. Made in the days when glass shards in the eyes were just a scratch.
The 2nd one, vacuum gauge, made me think 'wait, I have a bunch of pretty old vacuum gauges. maybe...?' Nope, they all have much more recent, boring dial fonts.
Anyway, that gauge gave me adequate font sample images of the missing numerals.
The 4 and 5 above still have a bit of perspective distortion.

Inkscape, thanks for the recommendation. My OS situation is
a bit very archaic. Still using a 'cut down' version of XP, but I see Inkscape does have a compatible older ver available. I will try it... eventually. The plan is to
upgrade switch to Win7, but only after I have a cut-down, sane-itized version, via the NTLite util. But this is a project I keep putting off due to too many others, and something of a phobia re wasting time stuffing around with endless Windows install issues. Life's too short.
SVG - unfortunately I have no SVG utils. Have been meaning to rectify that (for web use.)
Just now looked it up:
https://dev.w3.org/SVG/tools/svgweb/docs/QuickStart.htmland came across this: "If native SVG support is already present in the browser then that is used, though you can override this and have the SVG Web toolkit handle things instead. No downloads or plugins are necessary other than Flash which is used for the actual rendering"
OK, which browsers have native SVG support, vs which require Flash for SVG rendering? I need to read more. I won't touch anything that requires Flash.
