Villiers double-box silencer?

I'm after one of these for a Mark III engine.

Two pressed-steel halves, forming two cylindrical chambers joined by a short connecting tube.

Attached a couple of pics.

Thanks, Nick

Never seen an original. Always thought the bodies were made out of tube, not pressed. The end plates are pressed and at one stage I did have a nice red gum die but it’s disappeared over the years.
I admire your hopes in finding a useable original but I think fabrication is the way to go.

I think the very first ones were tube, and they had aluminium ends joining it all together.

Later ones were pressed - indeed, maybe out of a single sheet folded over and riveted - there's a 'bead' along the outside of the short connector between the two boxes on the later version (Mark IV) which suggests it was a flat part folded over in two after pressing both halves of the boxes in.

Yes, the ends are pressed - three designs as far as I know - plain circle, and long and short offset tabs.
