Design Studio 1.2 SDK

Hi ,
I am using an old version of SAP DESIGN STUDIO(1.2) . Apart from the basic components i need some advanced components like slider bar gauge etc.
I came to know through SAP SCN that it can be achieved Through installing sdk

(KarolKaliszDesignStudioSdkPack ).

For design studio 1.3 i am getting the sdk zip file at Release Adding Custom Css Collector · KarolKalisz/DesignStudioSdkPack · GitHub.

Any idea where i can get the SDK for design studio 1.2  ?

Thank You
