Subject: Contract Change Proposal #9, Additional Contract Item,
Oblique Position Indicator
Reference: (a) Contract BC-200 dated 7 December 1956
(b) Telecon 9 October 1956, LK to BPM
In accordance with your request in the telecon of reference (b) the
following proposal for an Oblique Position Indicator is herewith sub-
mitted. The requirement for this indicator rises from the need to have
a definite identification of the oblique position of the camera at which
each exposure is taken for ease in photo interpretation.
One (1) Oblique Position Indicator will be required for each Model 73-B
Camera. It will be mounted on the inside surface of the bottom of the
Platen Support Structure and will bracket the Data Recorder Assembly.
An image that will indicate the obliq ue position of the camera will be
projected onto each frame ? just outboard of the Counter and Clock data
information on each film strip. The present area of the field of image
will not be decreased. Each successive oblique position of the lens is
in increments of 24? 30' from the vertical. These images will indicate
the oblique position by marking the film as follows:
74 L (3rd left oblique)
49 L. (2nd left oblique)
25 L. (1st left oblique)
V (vertical)
25 R (1st right oblique)
49 R (2nd right oblique)
74 R (3rd right oblique)
The oblique position image to be projected will be brought into correct
position by a gear arrangement actuated by movement of the Oblique Unit
Assembly. One lamp will provide the necessary light for the images on
both frames and will be actuated by the same pulse that actuates the
clock and counter image.
An Oblique Position Indicator Set will consist of two (2) indicator blocks,
one (1) light chamber, and a gear drive assembly for each camera.
It is proposed that one (1) Oblique Position Indicator Set for each of the
sixteen (16) Cameras Model 73-B be added to the reference (a) contract.
The price for the design and manufacture of the Oblique Position Indicator
Set is $1, 250.00 each for a total contract price increase for sixteen (16)

Indicator Sets be assigned to the contract as follows:

Delivery of all Oblique Position Indicator Sets will be made by 15 May 1957.
These units will be designed to permit easy installation in cameras in the
field and will be furnished as field modification kits for those cameras
which are not modified in the factory.
Camera Model 73-B, #1 is presently in the factory for Maintenance and
Over haul. Serial #2 and #3 are expected to be returned for Maintenance
and Overhaul in the near future. It is. anticipated that these three (3) units
will have the Oblique Position Indicator Sets installed by the time they are
ready for re-deployment. It is planned that Serial #11 will be the first
unit to be delivered direct from production with the O.P.I. installed.
Serial #4 is not available for modification. Serial #5, #6, #7, #8, #9 and
#10 will be provided with field modification kits at the Detachments for
their modification.
It is estimated that the field modification of each Camera 73-B can be
effected by our Field Service Engineers in approximately ten (10) hours.
C
Factory Maintenance and FAK spares for the Oblique Position Indicator
will be. added as line items to Schedule III of the reference (a) contract.
Configuration B System Handbooks will be revised to reflect this equip-
ment modification.
We trust that this proposal meets with your approval and request that we
be given authorization to proceed with the manufacture of the Oblique
Position Indicator.
Very truly yours,
HYCON MFG. COMPANY
