Releases for Old/Antique objects

[Russell]

Can anyone advise on the Release requirement for old/antique objects in order to sell them as RF?

 

For example does a photograph of an antique clock require solely a property release from the clock's current owner, or does the original designer/manufacturer still retain any design rights in the object?

 

If the object carries a visible makers name does this alter the requirement?

 

Thoughts much appreciated.

 

Thanks, Russell
