About this model

These are trumpet valve guides originally made for an old King trumpet. Seems to fit many models of Bach, King, and Conn trumpets. Im not 100% of the model but its seems too be most similar to the model 180 valve guide. I'd reccomend PETG or Nylon for long term use, but I've been using a PLA one for a year with no issues.
