Conventional Fixtures Help Identifying old units

[cbernier01]

Hey Everyone. I have some old Century units here at the college. They work fine and are in fairly good condition. My only issue with them is that I have no idea what they are.
The closest I've been able to determine is that they are Century 2341 Units. That was determined by measuring the beam spread.

However, as I was cleaning one last night I managed to get enough of the paint off an ID label to see that they're marked as Century 1491 units. My problem is that I can't find any information about that type of unit on the web or in the Photometrics Handbook.

Any help would be greatly appreciated. Thanks!

See Posting pictures on ControlBooth. While the catalog number may not mean anything, chances are some people will recognize them on sight.

The only problem with that is that they all look the same from that particular period. In the Photometrics Handbook there are about 6 units from Century that all look like the ones that I've got.
