HP 8761B SPDT RF Switch

I have looked for other SPDT relays etc but not found anything very close to this (apologies if I’m overlooking the obvious)

If anyone can help me with this or point me to a similar euivalent model it would be really appreciated. Its just for fun/hobbying at home so I could also cut&paste but I’d prefer to link it to the rest of my Fritzing design.

The version I have has 3 SMA-F connectors and two filtercons

**Datasheet​❗**  
The data sheet can be found here:  
[8761A/B Microwave Switches | Keysight](https://www.keysight.com/nl/en/assets/7018-06828/data-sheets/5952-1911.pdf)  
(note: most of the images in the datasheet show type-n connectors but the dimensions of the metal body are the same)

The standard SMA connectors are approx 6.3mm diameter across the threaded part and aprox 5.3mm diameter without the thread.

The filtercons are 5mm across the flats of the hexagonal mounting parts and 2.5mm diameter at the end of the solder stub.

Any tips or suggestions would be greatly appreciated.  
Does anyone know of a part or symbol I could try to use as a starting point?  
I’ve tried to read through the info on making a part but I’m a bit lost
