I don’t get it. You’ve got a Hammy - an Olwell (particularly a Pratten) is not particularly different (or better).
It’s about the tone and timbre, personal tastes!
I love my Hammy but I prefer a bit more the Olwell timbre, despite it’s not powerful as the Hammy’s one…

I believe David Levine has a 6-key Olwell for sale. It was for sale in July 2014. don’t know if it was a Pratten model?
Thanks Tom–
Yes, I do have an Olwell for sale. Pratten, six keys, cocus.
I could be convinced to sell it.
