do you know makers of polymer smallpipes?
I’ve found only this italian:

i’m looking for a Hummelchen or a biniou koz
Try Andreas Rogge.
He makes hummelchen pipes, and he certainly works in Derlin.

i’ve tried this german maker, that has very low prices for his wooden hummelchen

I know that ‘Dunbar Highland Bagpipe Makers’ now make full Delrin/Polypenco pipes, and may possibly be able to assist a small custom project for you, worth a try getting in touch with them? 
All the best…
If you’re after a delrin SSP, the obvious choice is John Walsh. he’s been making excellent smallpipe sets for quite a while out of synthetic materials.
Not necessarily in Europe, where the import duties/taxes etc. may significantly reduce their attraction and you’ve got Ian Kinnear (who still makes some poly pipes but isn’t actively advertising them) and others to choose from.
But wasn’t memling after ‘a Hummelchen or a biniou koz’?
Oops. Mis-read the OP…
many thanks for the answers.
I would like to buy a hummelchen for the fingering very close to the recorder. The biniou koz because a friend of mine has a bombarde and we like breton music
