English Law/Patents Certificates, Diplomas, Licenses, CVs

I am translating an Irish birth certificate. In the left-hand upper corner, there is an abbreviated word - ''COMP.", just as in the specimen below:


''(in upper left corner; with the number 2 printed underneath)
*Comp.* Y 2504
Birth Certificate issued in pursuance of Births and Deaths Registration Acts 1863 to 1952.
(in upper right corner)
Form A2
Issued under the * S.W.A.
(asterisk explained on right side)
*Here insert the name of Act under which the Certificate is issued.
Births Registered in the District of Coom in the Superintendent Registrar's District of Killarney in the County of Kerry.
(The following information is entered in eleven columns on the certificate.)
1. No. 55.
2. Date and Place of Birth,..''

This specimen certificate can be found here: http://tinyurl.com/come63
The one I am translating looks exactly the same.

I just need to know the full word.

Any help would be greatly appreciated.
