Howard, I think you are right. It would delaminate if it got too much water and no dryout time. I have a modern panel board which i guess I will have to use, but held out hope for the original stuff as it served well in the mayfair hardtop.

Don't think Sears has ever made anything--just contracts out & specifies a few differences. Puts their name on a sometimes stripped down version of one the manufacturing company is selling alongside. Kenmore by Whirlpool, Norge, Frigidaire et al and Allstate by Kaiser-Fraser. Wonder if a manufactured by K-F tag was on that car.

I looked everywhere on it. It says "Sears" and "Allstate" on the front and "for replacement parts and service" on a sticker on the back. If you want close up pixs I will do that for you.

Randy, my guess would be they were probably an asphalt impregnated cardboard. Don't know but am thinking it might have been a different formula of what they used for the door panels only thinner-- almost looked and if I recall, felt like they were a really heavy type roofing "tar paper" type material. Have seen some that had kind of de-laminated and could almost be pulled apart in layers but in the heat still felt a bit sticky.

Out of about 70 cars there were 33 Packards at the event this weekend, and as soon as I get my film processed (no need to comment on my choice of imaging systems) I'll begin to add some of them to this thread. They ranged from a 1925 all original coupe by Merrimac to a 1947 Custom Super Clipper club sedan. There were 3 1941 180s, all with factory AC! And perhaps the rarest was the 1934 LeBaron coupe that was later (factory?)-refitted with a 35/36 front clip and leather roof and blanked rear quarter windows. Judging results included several 100 point cars.

There were also Franklins, Lincolns, Rolls & Bentley, Delages, Caddies, Lincolns, a 1923 Kissel, an alleged LeBaron Hudson Super Six, etc. But perhaps the two non-Packards that caught the most attention are worth putting up here. First a 1939 Rolls PIII (V12) bodied after the war by Labourdette of Paris, said to be the very last Labourdette coachwork done. Styling is controversial and beauty subjective, I won't impose my thoughts by my own word choice, you form your own opinion. Unique nonetheless. The second (photo to follow) was Judge Cassini's 1927 Isotta Frachini 8 (8A) bodied by Fleetwood no less!

Does anyone know what the material was for inner panels in group 30.2970?? It appears to be some kind of waterproof cardboard, but I can't find anything to substantiate that.

Yes. much better. It looks like initial drawing had the parts reversed. If the rectangle piece is bolted to the door then that ratio looks to be about 4:1 but the idea is the same. The spring could also could be shorter-but stronger than the Packard.

If ZIS piston is maybe 5-6cm diameter then I think both would be somewhere around 35 bars pushing window up. ZIS used lower pressure, wider cylinder--Packard smaller cylinder but higher pressure. Packard also had slight mechanical advantage with ratio. But now on to the next subject--I think you said solenoid valves

Brian, How big of a vacuum leak would it take? Almost mentioned that in my post because it needed the enriched mixture but first question post said it was running nice and smooth otherwise. Figured any vacuum leak big enough to cause the hard start would make it run like crap. Not being much more than the basics of an engine guy, what am I missing here?

Here's a thread from last July, same subject:

I suspect you've got a vacuum leak somewhere. Choking the carb is helping to offset the excess air.
