I agree with Wert that your stamp does not have the major re-entry C9ii. Your stamp appears to have extra inking.
Unitrade states that "Variety C9ii occurs on Plate 2 UR, positions 14, 19, 24 and 34, and that each is slightly different. Positions 14 and 19 also show slight doubling of the left frameline."
I don't have this variety and don't remember where I copied this scan from, so can not give proper credit to the company/person who had presented it online.
The doubled right frameline is best compared with the top frameline, which is not doubled.
