Agfa Standard 254? Analogue folding camera

1926-1933. Folding, rollfilm camera. 6x9.

I suspect this is the 254. A beautiful instrument with a small flaw. The focus knob (on the left) is stuck. I don’t want to force anything, but an expert will probably fix it easily. Nevertheless, it remains a nice collector’s item.
It has signs of use, as you can see in the photos.
With an f4.5 10.5 cm lens. The shutter works just like the release. The bellows is in order.
The items are securely packed and insured for shipment.
