any comments ?

The Marchal types that can be incorporated in the body (types E15, E18 and E23 in the link in the other topic) vary in housing-length from 205-280 mm. It would help if we would know / could calculate the (2) sizes of the ones in your Atlantic pictures.

Judging form your upper picture, I think this could be the slimmer Marchal type E18 we have here, with the Marchal logo on the upper side and no mounting screws visible outside (so no E23 becaus that is screwed from the outside / also not the E15 because it looks broader).

You could also email the guys who made the Electron Atlantic recreation, maybe they know ?
