Doorbell

It is interesting that we have been living now in this house for five years and still, we don't have a doorbell working.
We have had some "modern" things on the gate and at the secondary entrance (via the kitchen), which worked so so, until one of them gave up fully.
There are traces of a traditional doorbell at the kitchen door, so that is something that will need furthermore investigation.
Now, when we moved (and even during the showing of the house) no working doorbell has ever been seen at the main door.

The previous owner left what he might have bought for fixing the problem for some possible buyer (with a better eye than us?), but apart that I can't find the button anymore, it looks a bit plain and boring.

Must have been something similar to this, that we have in pieces somewhere in the basement. Doorbell from Byggfabriken

Inspired by Villa Florens in Malmö, I went and search for some second hand doorbell, with the difficulty that the space on our door frame is very tiny, and hence, limiting the research basically to nothing.

A wonderful example of a jugend doorbell. So beautiful but also huge. From Bukowskis Market

I ended up buying a product from the german Ebay that looks pretty ok and fits the measurement, but it is newly produced (so there are chance it is going to work without too much fuzz, maybe?) and maybe doesn't seem hyper genuine, but whatever.
I can't break my head on everything right?
I have now to "just" try it out and see if the whole ringing thingy is working still....(probably not?)

Longing to test it...!
