I noticed that several minor league teams in the 70s and 80s also wore minor league caps. Only two of them were actual Padres affiliates. Why use a bell panel when you're not a Padres affiliate? It makes no sense to me. Many have never noticed that the shape is a bell, they probably just liked the look. That's why when the Rays wear their 70s "Fauxback" uniforms that are 70s Padres rip-offs, it bothers me.
Anyway, here are the minor league teams that have worn these caps at one time or another. From what I can tell, most wore these for only one or two seasons. Unfortunately, finding minor league photos is a challenge, especially in color...
First, we will start with the Padres affiliates...
1978 Reno Silver Sox
1983 Reno Padres
1983 Las Vegas Stars
1983 was the inaugural season for the Las Vegas Franchise. They wore the Taco Bell cap only that season. In 1984 they switched to a solid orange cap.
2016 El Paso Chihuahuas
Now the non-Padres affiliates...
1978/79 Spokane Indians (Mariners affiliate)
1982 Tucson Toros (Astros affiliate)
1982 Buffalo Bisons (Pirates affiliate)
1984 Salinas Spurs (Mariners affiliate)
The second California League team to wear this type of cap.
-Unfortunately, I cannot find a photo. However, I have seen this cap in an old program that didn't belong to me. If you have a photo please email me.
Are there any I missed? If so please email me.
