Yep, I like #3s and #5s mostly. I posted these photos before on another thread, but I'll put them here for you. It's a 3-7 from about 1961-62. It came from an Antique Mall in Virginia.
Here's one I think I've posted a photo of before, but not in the Model 3 thread. It was bought by a gentleman after reading an article about Bo in the December, 1953 issue of True Magazine.
Best,
