Thank you Annes, Ivo & guest.
Your comments noted and no action taken.I do know that Forrest Poston takes all reasonable measures to identify his items accurately and did not mean to infer any complicity on his part.
I finally managed to replace the rather fuzzy pic of the Chinese one (Java hitch) with this taken head on
plus added comments.
Sorry for making you squint Anne.
Thank you for the links, guest. ...very interesting.
Proving that a certain design is copied from another must be a nightmare not to mention the cost of defending registered designs. I did not know that there was such a thing as a design copyright. How does it work ? Which body does the registration ?
I have worded this topic a little more sensitively on the site...erring on the side of benefit-of-doubt.
It's instructive to remember that in the glass world generally where copiers went on to develop and improve upon a design or design concept we talk of "influences".
Here there are small differences in shape plus obviously the casing, which is why I asked the question. However I do find the similarity of shape suspicious, yet there would need to be more similarities than shape alone to be considered a copy I guess.
The color is difficult to compare beause of different lighting conditions and different color of background, but yes I agree that from the photos they do NOT seem to be the same shade.
The quality of the glass does seem different although I don't feel able to judge which is better by sight alone. Ivo does not comment on quality at all.
