My Master V goes from 0.1 to 16000 ASA! - suspect the 3 is similar.

The III is quite different to the Master. It uses Weston film settings for film speed. I have Sngamo Weston's 1961 Advert open beside me, as I write. It goes to 5,000 Weston (New) whichis the same as ASA/BS arith, the II uses a different Westo system.

Beware also the cells don't often read fully after this length of time, that goes for later models like the IV's and V's as well.

I'm no expert in Weston meters, but I thought the Master II was the last to show Weston numbers. I've used a couple of Weston IIIs, though for the past 25 years.

My Master III (in front of me now) has Exposure Index (ASA) from .1 to 3.2M

EDIT: There may be a difference between the black and chrome-colored Weston IIIs. The black one was British-built and the silver was US-built. Notice that the black one is clearly marked "Weston Rating" but the silver one is not:


EDIT: My Master IIIs are all silver colored.

Brian, the photograph in the Sangamo Weston III advert is clearly marked as Weston speeds, as is the wording in the advert, but of course as the speeds are BS/ASA they may well have changed the markings on the scale.

I have a dozen or so Westons, and have looked at a lot more, and it has been my experience that a II or III is more likely to be still working (and can often be found near new in the original box with wrapped cord and everything for $10) than is a IV or V. I like them for use with older cameras and lenses that aren't marked in the current scale of speeds. For those, I have a Euromaster and a Euromaster II. I should probably have a V rebuilt while the service is still available.

Who rebuilds them? How much is it? I have a dead V as well as a live one.

I'd recommend Quality Light Metric in Hollywood, California. They've worked on a Weston III, a V and my Euromaster. Usually the selenium cell needs to be replaced or the meter needs to be re-calibrated. They did an excellent job. Do a search under their name to read comments on their services.
