Doesn't make them any more valuable than and other Durant. Durant / Star / Rugby / and other makes are considered orphan cars and as such do not command big dollars fully restored. Old Auto's paper out of Ont did an article on what's it worth and as luck would happen they had a rare 1932 618 Durant with all the bells and whistles it could ever have, side mounts, trunk on the back etc. Worth $14,000 Can and said it was worth the same 20 years earlier because of being an orphan car. AACA club echoed the same thing a few years back about a 1933 Continental Beacon Coupe and not worth much. Its a hobby and we pay more restoring them then we will ever get back.

You can't go by the Registry in DMAC which hasn't been touched since 2006 and isn't correct in places. Most of it was privately compiled in the 80 / 90's and based on hunches at times. The owner didn't believe in the Dominion Motors 1931 - 1933 alpha vins A - P minus I, O, N and used the T or made up a US plant in the case of the Frontenac. Fronty was all Canadian car.

The engine will have casting dates head and block plus a serial number on a boss at back of manifold on the block. You won't find a 22A engine with 1932 casting dates and its long been thought Dominion Motors used up existing US parts to create the 31 / 32's. The 32 Durant's and 1932 E 670 Fronty all have casting dates in 1931. In 1932 Dominion changed the 22A to 32A on the later 618 / 633 Durant and 685 Frontenac. That's another thing .. What does the VIN plate say on yours, Durant Motors or Dominion Motors for Durant Motors, out of Leaside ? Leaside became totally Canadian owned and operated Jan 14 1931.

The one piece Swallow rad cap was used on De Vaux, Frontenac and 618 Durant. The aftermarket catalogues specifically say E Fronty and 618 Durant. You could however buy the Swallow to mount on existing Durant 30 - 32 caps. So I assume you drill the flat spear type Durant cap and bolt it on.
