Everything you never knew you wanted to know about the Mercury Project
February 1962 edition of SEDR-104

Foreword Text
Here is the exact text of this edition of SEDR-104, I've added links as appropriate.
The purpose of this document is to present a clear, operational description of the various capsule systems and major components. Two types of use for the manual are visualized. The first is an orientation-indoctrination type document. The second use is as a reference document containing relatively detailed information on all systems and components.
The manual is divided by capsule systems. The first part of each section is devoted to the description and operation of "specification compliance capsule" system. Capsule number 19 is the specification compliance capsule. It is a manned three orbital capsule and is representative of the Mercury Program. Immediately following the specification compliance system coverage is the Test Configuration Capsule Coverage. This area compares the other capsules to the specification compliance capsule or to a prior capsule. The capsules are compared on a, "like specification compliance capsule except as follows" basis. The Test Configuration Capsules are compared to the specification compliance capsule system or to any other preceding capsule depending on which reference causes the least duplication. The reader will not be required to refer to more than two prior capsules systems including the specification system. Separate information is provided for each capsule test configuration, when the information is the same for each capsule it will not be repeated. All capsules will be covered in this manual for one revision after the particular capsule has been launched successfully. After that date they will be dropped from future issues.
Capsules numbered 2, 3, 4, 5, spacecraft 6, 7, 11] and 14] are covered in the 1 February 1961 edition of SEDR-104 revised 1 August 1961. Capsule number 8 is covered in the 1 November 1961 issue of SEDR 104. Capsule No. 10 is an orbital training simulator and altitude chamber test unit. The configuration of the capsule is subject to change during various phases of the test program; therefore, this capsule is not described in this manual. Capsules numbered 10, 15, 17 and 20 have been assigned an eighteen orbit mission and will be covered in SEDR 104-18.
All capsule configurations are not finalized as of this printing, additional information will appear in subsequent revisions to this document, reflecting changes as they are incorporated in the capsule.
Scope
The 1 February 1962 edition of the SEDR-104 Mercury familiarization manual provided specifications for the following capsules:
Specification Capsules
The foreword lists Capsule 18 as a specification capsule but it is listed several times in the body as a test configuration.
Test Capsules
The Test Capsules had specific differences from the specification capsule called out.
Excluded Capsules
In addition the following capsules were called out as having been assigned to 18 orbit missions. They were not otherwise specified in this edition.
Note that Capsule #20 had previously been considered a specification capsule in the December 1959 edition of SEDR-104
