Stuck focus ring of Carl Zeiss Jena 135mm f3.5

Hi,

So I bought that used lens, Carl Zeiss Jena 135mm/f3.5. In normal horizontal position or facing down the focus ring stops solid at around 15m just as it should at infinity. When I tilt the lens just slightly upwards, the focusing gets beyond 15m and up to infinity smoothly as it should, but I have to first get back a bit to say 10m and forward again.

So something stops the ring at 15m unless the lens faces upward. Is it any known issue?

Thanks,

Andy
