I have some new (to me) tools that maybe someone might recognize. You can look at the in my tools album user cp photos. Or if someone more IT savvy could attach them to this post.
Thanks Terry. So the long bar is for installing the valve and guide into the block, that’s what I thought. And a couple of valve spring compressors to install the keeper. No idea what photo 7 (counting left to right) is?
I added a few more pictures and I see of it! Indeed it is a cylinder ridge reamer and I understand how it works. It came in a metal box with a New Britain label. Also in the box were another set of cutters for larger bores and three more tabs to position the cutter on the block.
