You won’t find any dead stock of that model very occasionally come up on EBay, there was one last year if I remember correctly. I had one they tended to be heavy weight and low middle.
Along with the Amplus they made two models that were fabulous bats actually made in Somerset. No one else had a shape like the distinction or Amplus with the high middle on our wickets it should not really work but it did. Unbelievable balance on the Amplus.
Things progress thou and change, when I was younger I thought M and H were the best I could buy maybe with Newbery and latterly Salix.
Today I don’t think I would use a Millichamp if I was given one.
They are overpriced and the marketing overtook the product years ago.
