Pool skimmer weir - What do I need?

[Fruitygalore]

I have recently purchased a house in Australia with a pool and the skimmer has no weir.

The skimmer opening is approximately 250mm wide and 150mm high. The following came out of the skimmer box and I presume this is the attachment to somehow attach the weir door too? The model number is 20796 although I couldn't find anything on Google about this.

Does anyone have any idea what sort of skimmer door I should be looking for and whether I need additional fittings to attach it?

The skimmer box doesn't have any holes/screws for a door to attach too.

I presume the attachment that came off the skimmer is not actually the weir although the piece the weir should attach too? The attachment dimensions are approximately 235mm L x 73mm H.

I'm wondering if I need a spring loaded universal weir like this one? Baker Hydro Skimmer Box Spring Loaded Weir Door – Epools Pool Shop

Is it possible to take photos of the skimmer mouth? It may help us see how a weir door is supposed to attach to the skimmer.
