Olds Trumpet & Cornet Ambassador and other professional models
The original Brass Valve Guides are no longer available from our supplier and these Nylon Guides and Seats are direct replacements.
We have tested these Valve Guides and Ring Seats in the following vintage OLDS Trumpet models:
Ambassador Trumpet both those made in Los Angeles and Fullerton
Ambassador Cornet made in Los Angeles
Mendez Trumpet made in Fullerton
These should work fine on many other models of Olds trumpet and Cornet valves. The F.E. Olds company during this time used the same valve guides and seats in many of their trumpet models.
