Linhof Technika 13x18: Rotating backs interchangeable between IV and III?

[Utrost]

Hello,

does anyone know if the rotating backs of a Linhof Technika 13x18 IV (5x7) is interchangeable/compatible with a similar Technika III?

Best regards,
Uwe

III, IV, IV have the exact same ring so they are interchangeable.

The II and earlier had a smaller ring that the later cameras and did not have the snap latches.

Thank you!
