The B-26 Martin Marauder had a hydraulic hand pump handle in the same location. I unfortunately do not have any good images of it.

Odd, I wasn't expecting the manual to show up. Anyhooo.....you can't download it unless you join Scribd
Hi Laurent,
I don't recall a lever with this S-shape on the Marauder. I've looked through 01-35EB-4 and 01-35E-4 parts catalogs for the long-wing models and there are no results for either 111759 or 311699, though both do follow Martin nomenclature. There are very few parts in the 111000 range in the Marauder, but 311000 is a common range for parts introduced on the B-26A, some of which were retained for the rest of production. It's a very busy week for me so this is all I can tell you for now, but I can check 01-35EA-4 (B-26 & B-26A parts catalog) and recheck the other two next week. I do not have access to the parts catalog for the short-wing B-26B. Neither number shows up on the Smithsonian's drawing list for the Marauder either, but they don't have every Marauder drawing. I do not know much about other manufacturers' drawing number conventions. Do you know anything else about this part?
Best,

That's for the Douglas Invader.

Hello Maty, thank you for your valuable and interesting information. Regarding this lever, I don't know any more, except that the person who gave it to me said it was attributed to a "MARAUDER" type aircraft. That's the only information I've received about this lever.
Thank you for your help.

Came across this drawing in 01-35EB-1.

Hi Laurent,
I've checked through the hydraulic drawings in my collection, and the hand pump installation drawing for all models is listed as Martin Drawing 270323. This drawing shows how the hand pump is installed on the plane and states that the pump and its handle are part number 1H260K (or possibly IH260K) from the B-26-MA through the B-26F, and 1H260KA for the B-26G. Both were made not by Martin but by the Pump Engineering Service Co. of Cleveland, Ohio (PESCO, who are still around).
I've also checked the parts catalog for the B-26-MA and B-26A (01-35EA-4), and again there are no parts with the numbers 111759 or 311699. In this catalog the pump handle's part number is given as 260K, Pump Eng. Ser. Co., Cleveland, Ohio. I went back through the other parts catalogs with this number in mind and sure enough, 01-35E-4 has a drawing of it and lists it as "260K - Pump (PESCO Cleveland Ohio)" while 01-35EB-4 lists it simply as "260-K - Pump". Here is that drawing, along with a photo from the short-wing B-26B pilot's manual, it's item #13 in both:
As you can see from the above drawings and the one Tony posted, the Marauder's hydraulic hand pump handle has two abrupt angled bends in the same direction, one in the middle and one near the bottom, instead of being shaped like an S like your part. This shape is consistent across manuals. You can also see this same pump handle in the photos of Flak-Bait's interior linked in the thread below on tapatalk, photos 3, 5 and 6:

This is all I could find. I hope this is useful to you and best wishes,

Hi Maty,Thank you so much for all your research. So, if I understand correctly, we should probably look for the trail of another plane?Thanks again, Maty, and thanks also to Tony.Have a nice day.Laurent.
Hi Laurent,
Yes, this part is most likely from another aircraft. I mainly have documents about the B-26, so I cannot help much with other aircraft. I did a few searches at WWII Era Military Blueprints & Manuals | AirCorps Library. No relevant results for either part number. Looking for "handle and pump" and there were 169 drawings and 3 documents, none of which looked the part. Searching for "hand and pump" yields 637 drawings and 30 documents and I do not have time to look through that, but that could be a place to start. Of course, they do not have drawings for every aircraft in the world. I wish you luck on your search!
Kind regards,
-Maty

Just had the opportunity to crawl through the B-26B in Akron last week at the MAPS museum, unfortunately didn't keep up with the forum while I was gone and missed this original post.
This aircraft was recovered in Canada after it crashed in 1942 on it's way to Alaska. I'd call the restoration a "good faith" restoration, they did what looked correct, not necessarily dove into the documentation as it's not a flyer nor normally open to the public.
You can see in my pics that there is a unmarked handle on the left side of the center console that resembles the handle in the image of post 10. Also, there is a round plate on the right side of the console where that image indicated the pump handle would be. Quite possible they put it on the wrong side.
You can also see that there isn't space for a long handle to operate at, or near, the floor as the co-pilot's rudder pedals have that push rods connecting the assemblies.

Hi Smutny,
Great photos. I agree with your assessment of 40-1459 as a good faith restoration and they've done a great job, however as you can see quite a few of the components had to be made from scratch and as such are not quite right. I had forgotten that the 50-hour inspection training films are on youtube, but they show the pump's location on the B-26C and are probably the clearest wartime footage of it:
View: https://www.youtube.com/watch?v=nL-87V5LRXk&t=1208s
The pump is the same in nearly all models as covered in post #10, though the equipment and fairing aft of it changes between models (B-26-MAs such as 40-1459 did not have a hydraulic reservoir selector lever as they did not have the emergency reservoir of the later models). As you can see, the pump is attached to the structural floor (which is a few inches below the floor panel itself) and the handle passes through a cutout in the floor panel between the rudder linkages and the pedestal. The unmarked handle on the left side of the pedestal in your photos is the parking brake lever. I do not recall the function of the round plate on the right side of the pedestal in your photo nor if it's original.
Best,
