Prickers and what they fit

I bought a rough tin for a Primus 210 (no stove). It arrived to-day. In the tin was a Primus branded burner spanner (wrench), Silent burner outer cap, and 8 prickers (a few other parts Non Primus no great value). The prickers came in a packet that states >
Pricker Number 4605, These will fit the following stoves'
No's 0, 1, 1S;R, 5, 5S;R, 10, 25, 50, 51, 53, 54, 71, 210, 510, 516, 601, 609, 622, 628, 632, 637, 640, 701, 732, 735, 741, and 747.
I measure these pricker wires at 0.4mm.
The wire from a wire brush I measure at 0.35mm So there can be no damage done by using this as a pricker.
Now I am looking for an inner ring for a 210 silent burner. Has anyone got one for trade or sale
