I had a couple of those old, non adjustable B&L scopes. And used a couple of others. I have very clear memories of what a pain those mounts were to adjust. While fairly tough, I've seen them put out of action by a hard fall on the scope. The scope would be fine, but the spring loaded locking pin would bend too much....
You can't run fast enough to give me a set of those mounts. If you want a tough setup, such mounts are available. I have several. E
If you want to sell, or donate, your B&L adjustable bases, you should post what you have in the free classified ads. I know that there are people looking for Winchester 70 bases and either plunger or spring rings.
