I never felt attached to any particular manufacturer, collection has by biggest number -
WMS WPC era
Capcom
Gottlieb
SS Williams
Five years ago Gottlieb was the biggest number.
And single examples of DE, Zaccaria, and Stern
I recently completed a whitewood build and discovered some interchangeability with Stern and Capcom, and some coils are also interchangeable with Stern & WMS.
