Thanks 93x64mm. I like the Lyman 35 and 36 because they don't hinder access to the safety. My Mannlicher with the cocking piece peep is a joy to shoot but just a little harder to harder to get to the safety.
The only thing left on my list is to try and track down a Lyman 50 for my Ross M1910 Sporter. They're like hen's teeth to find!
