US Twinmill - Common Hatch Details
  • Originally there was one Hatch, which received changes until it was ready for production, then 3 additional tools were made
  • The Hatch Bolt Pattern is like a fingerprint with each one slightly different.
  • There are several differences but to tell them apart from the outside it's easiest to view the bolt pattern on top of the Hatch
