Hi Tel
what do you think about a Grammo but it is 120mm - it's nearly in perfect conditions incl. the black rubber cap.
How much you prepare to pay for it?
I got a Vitus in 110mm. (Has been told it is a VItius butthere is no labels on it)It ís kind of like the 3TTT but less oversized in the horizontal part... could be yours for £30.
