German prop cowling/spinner I.D. help

Very interesting, probably VDM type spinner. The data plates look genuine but it would need some serious forensic work to read the numbers, if they are there, this spinner is only partially made.
It is not quite the same as the various Bf 109 G spinners, it has a front opening reinforcement and the diaphragm is unusual with bolt holes for the prop hub mount and it has a reinforcing ring riveted on it. This spinner has yet to have the blade cut-outs or the rear mounting segments fitted. Unfortunately, I do not have the production drawings for these.
Overall, I would guess this was designed for a late prototype with an engine cannon. There are really only the Bf 109, Do 335 and some Fw 190D and Ta 152 versions that might spring to mind. It might, of course, be designed for the 4-blade applications. The seemingly partial reinforcement and different diaphragm lead me to suspect it could be for a DB603 powered version, but no evidence.
I add a photo of a Bf 109 G spinner inside. They do vary, but mostly in the style of cut-out supports.

Thanks so much for the quick reply and research notes! my friend here in Prague did
not think it was 109; maybe Ju86? but you have a great point maybe the additional section with cutouts still could be fitted..
