Thank you to everyone, for congratulations, inputs, advices and suggestions. Thank you Carlos for uploading photo of this replacement part, I will for sure look for this aluminium part after initially testing out a kind of repair that I for some time have wanted to test out on metal parts. Photos of that will follow,if it is successful.
I will have a closer look at the horn, and see if the elbow has the correct screw fittings for the horn, thanks for suggesting that, Jamie.
Curt and Roger, yes I know this was a very lucky buy, and also, I was checking the ad at the right time, and was only 30 minutes away from the seller in driving distance etc.
I was absent from the forum yesterday evening after feeling a bit strange...after licking the horn yesterday morning, it became too difficult to avoid tasting the green mint color
But honestly, I did not know they used arsenic for painting the horn in a green color.
I know you are curious about the price paid. I really am a very humble guy, living VERY sparesely and not owning much outside my gramophones. I am also not even remotely close to have a bragging character ( and always very sensitive to other peoples feelings), and I am also very aware of that I live in an area with prices that are impossible to find in other part of continental Europe, also due to an obvious limited interest in antique gramophones in my area. All that said, I paid the set price €150 for the Pathéphone.
