Thanks Eng. We have a lot of BMW 801 parts, including a full set of cylinders, and 2 of the 3 center section pieces. Someday, we hope to build up a display engine; mocking up the parts we don't have. Knowing that one valve is from that engine is just one more nice thing we have to go with the...

I have two more valves we found, and what looks to be a door or cover of some sort. The first valve is the same style as the ones for the DB-605, except it heavier and longer. Also, the face of the valve is convex. There is a number stamped around the stem end of that valve. It is 18WCV772012...

Thanks, Eng. Does anybody have a print for the cam-carriers?

Thank you mjfur. I went to that website, but it is all in German. How can I get it translated into English so I can tell what the item really does? I understand that it is a piece of radio equipment. ----- Larry

Thank you, Engineman. Now I can make new signs, with correct information, about the cylinder bank. There is a piston in each cylinder, but they are corroded in place. I will have to make a fixture to hold the valves for display, after I get the rest of the valves cleaned up. We have a cam to go...

I'm back from the Freeman Army Airfield Museum seeking some additional information. Our president was doing some reorganization in what we call the "dig room", where we have parts that were buried in the late 40s, and dug up in the late 90s, but have not yet been cleaned up or identified. He...

Ratier prop hub mystery solved. The German Henschel Hs 129 (we had at least 1 here at Freeman Field) used a French engine and the Ratier prop. It turns out that we have a previously identified blade from a 129, and it screws right into the hub. Powerplant: 2 × Gnome-Rhône 14M-4/-5 14-cylinder...

To the best of my knowledge, they were burying; not selling for scrap. They did weird things after the war. For example, there were a lot of hand tools, like wrenches. They paid people to use a torch and cut them in half, and the bury them. Why not just give them away? Makes no sense. The parts...

Yes, I think you have provided enough info about the main bearing cap. Thank you. It was a challenge to find all the markings, clean them enough to make them visible, but not damage them. I appreciate your encouragement to look more closely. Maybe one of these days I'll learn to not be in so...

Thanks, Rob. Makes me feel good. But I was thinking that extreme close-ups of scratchy numbers aren't very exciting (except for Engineman).

OK Engineman, you are of course correct. There are additional markings on the main bearing cap that I was not able to see in the relatively poor light at the museum. I brought it home for closer examination. I found 4 more separate markings. 2 of them are on the curved edge of the bearing...

Oh, OK, thank you. Larry

@Engineman Thank you for the info (with documentation!) on the DB 601 intake manifold, and the main bearing cap. I will examine the bearing cap more closely to see if there are any edge markings, as you have suggested. If there are, I will photograph them for you. Larry

For Engineman, and Tom Fey: Thank you for your prompt response to my inquiry about the prop hub, which turned out to be a Ratier hollow shaft electric propeller system. I have passed that info on to the two volunteers who are working on this item. Since we at the Freeman Army Airfield Museum...

When Engineman ID'd a propeller for us about 2 weeks ago, he saw a prop hub in the background of one of the photos. That hub is for an Fw-190. But we do have another prop hub that we have been cleaning, and we don't know what it is for. We have now removed enough crud that you can see some...
