I can't be totally sure based on a single small line drawing, but I'm 95% certain my model is built from the Vic Smeed Lorraine plans, given that the hull dimensions are identical; the differences from the drawing are presumably a combination of artistic license, the techniques/materials used by the original builder of the model, and my model being the hard-chine version rather than the rounded displacement hull depicted in the drawing.
I'm certain it's not built from a commercial kit (though it may possibly have been built using a kit plan) as all the structural parts have been cut by hand and have no markings or outlines printed on them, and many appear to have been cut from scrap wood salvaged from old furniture!
(The "stanchions" are actually homemade items made from split pins inside lengths of brass tube, with copper wire threaded through them, and other than a few interior details are the only fittings on the model.)
The Keilkraft Meteor has some similarities, but is significantly smaller (38"), has different hull proportions, and no forecastle. Similarly, the Dumas Dauntless lacks a forecastle and has an odd cabin layout (with a very low cabin forward of the main wheelhouse, which has an open back) not found on my model. Here's a photo of a built one:

When I rebuild the model I'll completely plank the deck (including the aft boat deck) and resurface the superstructure with either mahogany veneer or (more likely, as it's much more durable) stained plywood, with appropriate panelling detail. I also plan to add bulwarks around the lower deck and rubbing strakes on the hull.
