Judging by the looks, the impellers are from the DB engines (Jumo impellers are fully shrouded; BMW impellers have straight vanes (besides the 801E, S and F, that were rare)). Judging by the size, the smaller should be from the DB 605A, the bigger should be from the DB 603A.Gold-tinted impeller: The number on it is D 1404. It is about 10.5" in diameter, and has a height of about 3".
Other, larger impeller: Numbers are s. 02 796, and NO 1037. It is approx. 12" in diameter, and 2.25" high.
Impeller dimensions for Engineman. These dimensions were measured with a scale marked in millimeters, and read directly in millimeters. They are NOT calculated from inches.
Smaller gold-anodized impeller: OD to tips is 265mm. Diameter of inlet tips is 152mm.
Larger clear anodized impeller: OD 305mm; inlet tips 160mm
Finally, thank you for your earlier compliment on my recent photography. The reason for the improvement is that I have stopped using my cell phone for most of the technical pictures I take. The cell phone is more convenient, but I have way less control over the result. I have "adopted" my wife's Nikon Coolpix P300 camera. It has a macro setting, so it will focus very close. I can directly control the resolution, so I get sufficient detail without getting too big a picture that hogs up file space, and takes a long time to transmit and/or load.

Yes, the big impeller is too big to be from the DB 603A, that was of 280mm diameter.Now, the larger impeller. The photo's and dimensions show from genuine original Daimler-Benz documents that it is a DB 603 L 2nd stage supercharger impeller.
This is a great find and it looks to be in good condition.

Perhaps it is from the DB 603L 1st stage, not 2nd?
BTW - do you know the diameter of the impeller on the DB 603E?
Thank you.It is a 2nd Stage DB 603 L Impeller, identified from original information, engineering drawings and data.
Hi,Thank you.
Can you share the diameter of the impeller of the 1st stage of the DB 603L supercharger?
Thank you.

He was testing us. I wasn't going to say anything.
