Adrian Pearsall chairs - Need help to ID  

Good eye for catching the joint angel discrepancy. This is often a tell for the Jacks table knockoffs.

However, I think the strap layouts and actual strap bracket design looks the same as the supports for my 1401-C chairs. Can you take a close-up of one of the brackets?

Thanks for your help cdsilva!

Here's the close-up

I think mine are similar, definitely screwed to the inside face like yours, but I'll check again when I get home this evening. I am fairly certain that my screws were not square heads (I replaced the crumbling old straps so saw these guys up close and personal).

Here are a few photos that show the strap layout (5 one way), clips, and partially-stripped slotted screws. The clips look to be the same as yours.

The clips really look the same.

I noticed that 2 clips were slightly moved from their original position, so I suspect that the original screws have been changed when the chairs were reupholstered.

OK thanks a lot. I will continue my research hoping to solve this mystery!
