Wild Heerbrugg T-2 theodolite eyepiece set, for high-elevation sightings

Description

Wild Heerbrugg theodolite eyepiece set
, for high-elevation sightings.
Here is a vintage, Swiss-made accessory set of eyepieces (one for the telescope, one for the reading microscope) for a vintage Wild T-2 theodolite.  By vintage I estimate the age of this set at 50+ years; note the leather construction of the case, not seen in modern times.  This set
may
fit other models such as T-3 or T-16, but I cannot attest to that.
Specifically, these are diagonal-extension eyepieces, intended for sightings/readings of high-elevation targets, right to the zenith.  Moreover, the telescope eyepiece has an
autocollimation port
for a plug-in lamp housing, which is also included.  This is rare in my book; I have never seen this style on the market, ever.   Sorry, no battery-box or power supply is available to make this a turn-key operation.
For those unfamiliar with autocollimation, the theodolite is focused at infinity, and the target is typically an optically flat mirror.  With the lamp housing plugged in and turned on, one will see an inverted return-image of the reticle which, when precisely overlaid on the real reticle, indicates that your line-of-sight is "squared-on" to the mirror.  This mode of operation is useful for many indoor/industrial applications, typically not encountered by surveyors in the field.
The condition of this lightly-used set is excellent; they spent much of their life in storage.  On exterior surfaces, just a few paint-rubs at the autocollimation port, and the scope eyepiece below the black-knurled ring. Please review the pictures.  The optical surfaces are clean and unscratched.  The autocollimation port has a diffuse green filter in the well.  The lamp and cord appears untouched; the cord is still coiled as if fresh from the factory.  The lamp housing is fitted with the old-standard incandescent frosted mushroom 4-V lamp.  A spare lamp is included.
Shipped via USPS Priority Mail, typically the same day, or next business day.
