@THED4NGLER Noting the excellent advice above about not fixing something that's not broke, if you ever need to pull your SVEA 123 apart, look here: https://classiccampstoves.com/threads/svea-123r-disassembly.32989/ Cheers Tony
You can get prickers dirt cheap, maybe fettlebox has them, they are on the bay. If you want a few inches of .006 wire i can send you some, get me your address. Glad you gott er running! I use mine a lot and love it!
The SVEA prickers come up on that auction site. The SIEVERT stamped ones are a lot more, but not the regular SVEA pricker.
I think it's a high C guitar string but you may also find that a wire from your household wire brush will work.
