It's been a while since I've posted anything in this thread - been having a couple of issues with the Minneapolis camera.
Here are a few shots from a couple of months ago:

One thing I'm fighting is camera shake - as you can see, even at higher shutter speeds it's a bit of a challenge. I may have to resort to using the camera on a tripod!
Speaking of tripods, the other issue that's recently cropped up is that one of my National Graflexes (yes I have a couple!) won't activate its shutter when mounted on a tripod. I'll press the shutter release button and nothing happens. I take the camera off the tripod and the camera fires. I checked the back, even swapped backs, but the result is still the same. Hmm may have to go back to Mr. Marshman for a look-see.
While the exposures generally look fine, the other thing I have to watch are light leaks, particularly around the edge of the mirror. I've figured out that I need to cover the lens with my hand when winding the shutter - hopefully that will solve the problem. Interestingly, in one version of the National Graflex instruction manual they actually suggest closing the viewing hood when advancing the film and resetting the shutter, due to the increased sensitivity of films. I may end up having to do that as well!
The second National Graflex has a roll of film in it and is raring to go. The one issue that I have with that camera is that the second shutter curtain slightly shows itself when I have the camera set on bulb time. I think in the case of this camera that's the way it is, as Frank went through this camera as well.
I've added a bunch of new accessories to the cameras kit, including two additional 140mm telephoto lenses (they're hard to find so whenever I see one available I snap it up). One of the telephoto lenses had what looked to be a large aluminum adapter for Exakta cameras, so I had to wrest that from the lens (don't ask!) to bring it back to original. Works great and looks great now.
I'm hoping to get out more and put these cameras to better use than simply around the house!
