Thank you, Special Ed. I'll have patience and wait to see if others on the forum come up with additional information. That blade was buried out here for some 50 years, and has been in storage for another 30 years awaiting cleaning and identification. We are interested, but in no great rush.The symbol W.Nr. indicates it is a German blade as it stands for Werk Numer with the serial No. of the blade. There are those here who will be able to tell more.
Thank you, Engineman. I passed the info along to the person who is working on the propeller project. In due time, the prop blade will find it's way into our Bf-109/DB-601 display. I'll post a picture when we get that far.Very nice Larry!
I agree, this 9-12004.10 is a blade from a Bf 109 F-3 or -4. This was designed for the new DB 601 E engine with a larger diameter propshaft spline and with the integrated VDM pitch change drive as part of the front engine case, rather than the earlier versions with an external VDM gear unit bolted to the front of a DB 601 A or N. The new Hub assembly was the 9-12010.21 and the complete propeller assembly (gerät) was a 9-12010 A. The overall prop diameter was 3.0m.
I see your photo shows the blade on a hub with a backplate. I can help with hub Identification, decode and location of the stamped data if you wish?
This blade is only listed for the Bf 109 F-3 or -4, but those aircraft types could also be fitted with the slightly later Bf 109 G prop type 9-12087 A. The VDM manual says that the F-3/4 had to have rear cooler armour to have the G propeller. However, I understand that the Bf 109 F-4Z (with GM-1 high altitude power boost) also had the 9-12087 A prop.
Please ask if you want more info.

All of the items in the display pictures are already identified. We don't put things out for the public until we know what they are, and how they were used.Hi Larry,
Great displays. There are lots of items there that are possible to ID. I will try to write a few clues from what I can see. As always, physical examination is best,
but numbers can be crucial, often just knowing which numbers and where to look!
I think your collection is important, I believe many of the captured aircraft are known-of and were carefully assessed.

I don't know. The next time I'm at the museum, and have a little time, I'll pull the brown item out from under the table, and get a decent picture. I'll also get a close-up picture of the numbers on the main bearing cap. ..... LarryHi Larry,
I was going to ask if you knew what the long brown metal part is under the table on the cardboard box? Also, if you have a detail photo of all the numbers on the top of that
main bearing cap (sat next to the Bf 110 right-hand DB 601 A/N Cylinder block on the table)?
Cheers

OK Eng, here you go. I was out at the museum this afternoon, and took some pictures. There are 2 pictures of the DB-601 bearing cap, and the numbers are very clear.I don't know.

You asked about the "brown thing on the carboard box, under the table." You're right; I don't know what that is. Maybe somebody else with the museum does, but I don't. It is clearly sort of smashed. It appears to be either cooling or exhaust.

Hi Larry,
Well, the "brown thing" is actually a DB 601 E/F or a DB 605 or DB 610 engine intake manifold. These were the same item. Specifically, it is a Left hand inlet.
I enclose the parts page from a 1943 DB 605 manual. You can see this part is number 1, 9-601.050-701, it has this 601 part number as it is the same part
as designed for the DB 601 E/F. Unfortunately, it is quite difficult to declare exactly which engine this came off, although there are differences in the attached
pipework on some types, but it is still tricky/impossible. Of note, the attached small bore pipework is the starting primer pipe, with the two Karcher spray nozzles
still fitted.
I shall get back to you about the bearing cap later today.
Cheers
