question Laycorn box joining studs / fasteners

[robin craig]

The humble Laycorn box, which seems to have been made by Permali is a great piece of kit.

 

I have found one person on ebay selling joiners for the corners but frankly I suspect these are a home made casting of something and not the real thing.

 

I am showing the box corners but know very well the boxes are not in their correct position.

 

Does anyone have any that they can show us or even point the way to where they can be bought from?

 

Thanks
