Tuning Where to buy piston Seals

I’ve got an RWS Model 45 made in 1984.
I want to replace the piston seal and possibly the spring if necessary.
Who sells these parts ?
I used to be a regular around here but have not been around in a year or two. So I can really remember where you guys get your spring kits from.
This will be my first time doing this. I’ve watch a few videos. I’ve made a spring compressor and already have the air rifle apart.
Any suggestions or advice would be appreciated
Thanks
 
These are great quality. The Pom’s love them and the strength of your dollar at the moment make them a good buy. There made here in Australia.
For future reference 🤓
 
I use all Vortek components. Tom is terrific to work with.

That's good information. I'm always looking for a source of seals and such. CF
