Glide-Slope Indicator?

[Bomber Bob]

I am looking for information on something that I believe is called a glide-slope indicator. What I know about it is:

It is labeled:

Weston Instruments Division

MODEL NO. 898 TYPE NO.15

MFR’S NO. 521273

The front has:

• A picture of a cross section of an airplane as viewed from the rear.

• The horizontal needle is labeled "U" and "D" which, I presume, means UP and DOWN, probably relative to the nose.

• The vertical needle is labeled "L" and "R" which, I presume again, means LEFT and RIGHT. Because airplanes tend to roll through turns I expect that this indicates roll direction rather than turn direction.

• There is also an indicator light labeled RELEASE.

The back has:

• A screw labeled “+” and one labeled “-“ which I expect are for application of 28 VDC standard aircraft power.

• There is also a 18 pin electrical connector.

• Eight of the pins seem to be connected together in pairs.

• Two pins (including one of the eight) are connected to each of the two previously mentioned screws.

• Three more pins (including two of the eight) are connected to the indicator light

• Four pins don't seem to be connected to anything

Thanks for any help understanding this.

my first thought is the turn bank indicator...

Is this similar to what you are describing?

Very similar!

Differences:

• There are some minor differences in the legends on the front.
• The picture of the plane is the same, but the Left-Right indicator on mine pivots at thee bottom rather than the top.
• Where your indicator has a large cap at the front lower left, mine has an orange lamp labeled "RELEASE."
• Mine only has one connector on the back (18 pins).

If I can figure out how to do it, I'll post photos.
