Is this solid silver Hanau?

[AllSeasons]

I took a couple of questionable pieces I have to a jeweler today, who thought one of them was plated, and the other one was not silver at all, but lead. As you can probably imagine, I'm a little deflated and starting to doubt all my silver pieces that are not 100% properly marked. I'm going to take the "plated" one to another place for a second opinion, since the jeweler didn't have an XRF machine or even bother to test the pieces with JSP solution. The lead one I'm sending back to the seller to get a refund, since I've always had my doubts about that one. The lead piece has a carved coconut shell in the middle, and the jeweler didn't even know what that was. So I don't know if I really trust them.

But anyway, here's a Hanau piece that I purchased a while ago. I was pretty sure the marks were Hanau, but now I'm not sure. It is a nice little handled bowl with cherubs that's gilded on the inside. Any insight and identification of maker would be much appreciated. And most importantly, is this solid silver?

Here're the images. Thank you in advance.

Hi,
Although image of the marks is small, I`d say it`s Hanau; typical style, too.
There is something interesting here; as if the whole bottom was cut in the form of an ellipse and soldered. Namely, there is clearly visible line of an ellipse, more so outside (my arrows) but also inside beneath gilding. I see no reason for that; the practice was observed by duty dodgers who had smaller pieces hallmarked and then back in the workshop transferred hallmarked sheet of silver to much heavier object (e.g. a teapot). But such action in this particular case makes no sense. It`s a mystery to me, because creating the bottom from a separate sheet of silver is not what was needed in the manufacturing process. Later manipulation is out of question because it was perfectly done with hardly visible solder line and gilding.
Try to take close up of the marks.
I suggest testing both the bowl itself and the ellipse where the marks are.

Crowned H (far left) and the mark on the right are B.Neresheimer and Sons.
So,that`s the maker in Hanau.
See here, you will find both marks (perfect match of all marks is not needed with Hanau silversmiths).

Thank you! This puts my mind at ease a little more. Upon closer inspection, it appears that the ellipse is tarnish lines. It also has short lines extending from the ellipse to each of the legs. My guess is that it was placed on some type of display that had an elliptical shape (for a very long time), which caused the tarnishing to appear in that shape. But good eye!

Interesting, yes you can see solder lines that extend vertically underneath the feet, and on the inside it appears the solder joint extends vertically to the top of the rim. I think this is due to the bowl being assembled from 4 side panels + 1 bottom panel (the ellipse).

My guess would be that this construction method allowed the chasing on the side panels to be stamped with a press or similar prior to assembly and after which, all pieces would have been soldered together.

Additionally, I think AG2012 is indicating that the dark lines represent a solder joint because the solder will have a different alloy composition than the bowl and will tarnish at a different rate, in this case appearing darker.
