I have had good luck with those found on ebay. I ended up buying several of each screw. Not sure if they are still listed on there but I found it easier to call the guy selling them and told him what I needed vs ordering off the website. A fellow member Louis Rotelli has also made me a few custom screws a year or so ago and they were exactly what I needed and of excellent quality. Good to hear from you! I had you restock a OO grade a couple of years ago and need to stop by your shop and see you again. Zachary
