Wanted: Radio Telephone Tower Components

We have three towers for our Radio telephone communication system- tower type '123' 38.10m manufactured by ELECTRIC POWER TRANSMISSION PTY LTD SYDNEY

These towers were built in the late 1970s.

I need to change some tower components, all parts are hot dipped galvanised(Australian standard specification - K.53). Steel was supplied by BROKEN HILL PTY. CO. LTD. This information is taken from the tower handbook.

Is there a company that is familiar with these towers and can manufacture these structures?, most of the items that needs replacement are less than 3 metres in length.

Thank you.
