Thanks for your kind replies!

The closest I managed to dig up is a fork style used with the Velocista model. The double lined „T“ stamp on the crown is also a bit faded on one side, I mean the depth of the stamp seem like it has been worn away, but only on one side, which is very strange. I’m suspecting at this point, that the fork might be much older, than the frame itself. There is an imprint on the fork neck saying „52“ and something like „S.V. 971“… Maybe 1971? Very hard to read…
