Marrakai--

Thanks much for the pictures--great repro!!

Heym surely does appear to have some type of 3rd fastener.

Guess there are no new Double gun makers replicating the dolls head and similar 3rd fastener.I think they look neat and classy.Must be the cost or modern steels showing pressure data that shows the such devices do not benefit the strength of the action or benefit its alignment upon closing.Logic would seem to conflict with that but--

Makes one wonder if the older guns with older steels really needed the 3rd fastener as a safety b/u when proofing/shooting the gun.

Johan- I would agree on the appeal of the Mckay Brown, I would be hard pressed to choose between it and the Purdey.
