Pinch Pontil………I always thought were CAC …. I have some the pontil is so hard to see . I use a jewelers lope and still cant tell if it’s a pontil or not. They are hand gathered. I keep them around and look at them once in awhile hoping I can figure it out. Transitional… I think need more research….Glad you posted something on this topic.!! I like you have hundred of them some are easy to see the type of pontil some not so easy. I do believe I have some like yours and Dave…..Dave not here.
