Goes to credibility, Your Honor. Proves that editorial opinions are based on first-hand knowledge and skill. Conflict of interest? Well, there must me megabucks involved if you decided to jump on the MCM gravy train, so that's understandable
(As for the skill part, can someone fix these ridiculous strings of quotes?)
While I suspect that Monogram based the kit on their Phantom II Henley roadster, all I can find about the car you're describing is that it's a 1929 Springfield Phantom I Sport Phaeton (which would explain why Art insists the Monogram kit is a Phantom I). Google that description and check the chassis/engine against the kit. I bet it's a Phantom II engine in the kit. In any case, I don't have any reference for that or any Phantom I. While the Monogram classics look great, they also fudged big-time on their kits for the Mercedes 540k cabriolet and coupe.
I went back to both the RHD and LHD manuals and the caption shows that both are indeed the automatic version. I don't have any reference on the manual version, but I did find a couple of dash shots that have a chrome T-pull on the left side.
FYI, if you want to build one of the Monogram 1931 Rolls-Royces, you'll want reference for the Phantom II. The Phantom I was discontinued in 1928. You'll find great info and images at rmauctions.com, and I have tons of material I can share with you. I also recommend that you follow Cato's Rolls Sedanca and Harry's Rolls woody threads in Big Boyz to see their Pocher builds.
I didn't see this mentioned earlier, so I hope I'm not being repetitive.... HP has just introduced a bundled system called Sprout, which includes a scanner, 3D software and a Dremel 3D printer. $2699. If you don't want the printer, they offer 3rd party printing services.
The only real substance of my post was to point out that there would be different elements on the dash between automatic and manual shutter control versions. The rest is just high-falutin' stuff to back up my observations. Just to be anal, Harry is basing his on the 1934 Star of India, so that would have an automatic shutter control. But we all know that Pocher used a lot of parts over on different models. If the chassis, etc., are all the same, that would explain why I've seen a complaint about the Star of India kit that the doors don't match the 1:1.
