High quality adapter

I have several M39 lenses that I use with my Micro 4/3 camera and this adapter is one of the top adapters I have. The machining is precise and the lens threads on smoothly and the bayonet mount is snug. The lens even lines up really well so you can see the focal scale while using the camera - not all of the adapters I have tried get this right. But this one did.

The only downside is I was hoping for it to be a little thinner specifically for 1 of my Soviet Made lenses.
