L. M. Prince Eng. Transit
For Display Use Only.
$450.00
Description:
This is a
very rare L. M. Prince model 1642 Engineers' transit. Even though this transit has some
damage it will make a nice addition to your collection. What makes
this such a great collectible is the fact that this instrument paved the way
for the shifting base on surveying instruments as we know them today.
This unique instrument is one of the many different methods devised
in the mid to late 1800's to allow the user to shift the instrument atop of
the tripod. In this design the engineers came up with a unique locking
system that when the two locking screws were loosened the user could shift
the instrument on top of the tripod to get precisely over the point.
From what we can tell this design of shifting base was only seen on
instruments that were made in the central United States. While this
design did not last long it was certainly one of the styles that paved the
way for the more conventional means we know today.
This instrument
has had a pretty rough life as the horizontal limb is bent. The
instrument does actually spin but the upper socket and circle is damaged.

Randolph Compass With Telescope
$1,095.00 Description:
This is a
nice TF Randolph compass with telescope. This instrument is based off
Randolph's 1879 patent of attaching a telescope to a compass. This
instrument is in pretty good condition as it has a slight bend in the
horizontal limb so when turning the telescope there is one area that is a
little stiff.
Other than that it is in pretty good condition.
If you want a nice little piece of history than this will make a great
addition to your collection.

Telescope Length = 7 1/4"
Height To The Top Of The standards = 9 3/4"
