Jimbeckwith, I have to sincerely thank you for sending me some good scans of these two great brochures. These are from the very early days of the DR. Just when it was coming online and was becoming a reality for GE to be able to sell. Notice that the OC-2 and the DR-2 were sold at the same time. No DR-3 though, that is what the OC-2 was for. Very interesting stuff. Enjoy! Oh, and I should mention that these files are quite large PNG files that you shouldn't download over a cell network unless you just have data to burn. I figured that you all would want the highest quality scans I could give to you. With Google Drive, I can! Let me know if anyone needs a JPG version instead. drive.google.com/open?id=0B8_jm7K-ahMaWjFFclRSOHA1TUU |

Fascinating stuff, I didn't realize the OC-2 was sold concurrently with the DR-2.
It's been said that the earliest DRs did not have a crankcase heater. It has also been noticed that crankcase heaters seem to be particularly important for satisfactory operation of DR3s. I wonder, then, if there were ever any DR3s ever released without a crankcase heater? If their introduction was delayed either because they noticed problems with them when run without a heater, or because they had excess OC-2 stock to get rid of, then I wonder if GE may figured out crankcase heaters by the time the first DR3 ran off the production line for sale.

Yes, this is interesting stuff. I had figured that they may have sold the DR and the OC at the same time but this confirms it.
The crankcase heater was absent from the very first DR models and was missing from all of the OC2 models. It just wasn't something they thought about at first. Apparently they did have issues that led to them adding it later on. Now, whether that had something to do with them delaying the release of the DR3, we may never know. Of course, I've said that before. People around here keep coming up with great mounds of priceless information!

Was wondering if we know the year and month the dr went into production?

1926 for sure. Late 1926. I almost remember it being October but I could be wrong.

Thanks Ray
Was woundering if the first DRs had (1926 ) or so had name plates on them or some way to identify them ?
The one in the antique mall I could not find a name plate on . And sense it had a tall control and a pig for evaporatore assume it
could be in the 20s . It's still there they just put big Pepsi stickers on it for some reason!

I'm honestly not sure how you could identify one as being from 26. The very first experimental DRs had a flat evaporator but by the time they were released it seems like they had the normal pig evap.

You could probably identify a 1926 unit by its serial number just as long as it miraculously avoided the rebuild shop.

Aerial number?
What is it and where would it be on fridge?

On some or all of the DR's, there's a serial number tag riveted to a fin alongside where the condenser tubing connects to the dome. It appears that this was removed when a unit was rebuilt.

Aerial number? What is it and where would it be on fridge? Sorry, typo. I meant "serial number". It is located on the nomenclature tag and should be on the top deck in front of the control. The first digit should indicate year of manufacture: ie, if the first digit is "9" it would have been manufactured in 1929. However, I must admit that I have never seen a serial number that begins with "0" (1930). |

Now I'm really confused! I have a DR-2 form F which is not a rebuild and its serial number begins with an 8. That seems far to early for a form F which I understood was introduced in late 1929. It has a 32 fin condenser and the typical oven type evaporator of a form F, though it has a float that looks more like a tea kettle (rounded shoulders and a valve stem at an angle) than the standard "ink bottle" style.

That is very interesting. I remember seeing a similar float valve on pictures of the very first DR machines. I've never seen one in person. All of the ones I've seen just have one width and no shoulders. |
