Good morning, Chaplain Jeff;
Well, no, not really. I am not a camera repair shop or a camera retailer. I probably have enough stuff around here to qualify for a small shop, but I am not doing that at this time. The use of the phrase "in stock" has been to indicate that the item is indeed here, and I do not need to order it or go out and get it. In my case, that does not mean that the item referenced is for sale. The Kyoritsu EF-511NK1 camera tester is here just for checking my own stuff, and the results of any repair efforts that are made on my behalf. A local friendly camera tech was a little bit discouraged when I insisted that a recent repair and adjustment was not satisfactory, and then I told him what I was using to check the camera with. All subsequent work has been fine.
I bought the Minolta Dynax 9 / Maxxum 9 just this year, mainly out of curiosity and a desire to run some tests on it with manual focus lenses and a mechanical/optical adapter. While I do not intend to sell this camera at this time, I might be able to suggest some sources for others that you might consider. I must honestly admit to you that I have not yet exercised all of the features of the 9. If anything, this camera was a precursor to what the latest digital camera wonders were going to look like. Yes, it is a camera for which the instruction manual is a needed accessory.
I do know that there are differences in the flash mount. I might have the correct adapter for it, but I am not really sure. As mentioned, I have not yet exercised all of the features of the 9.
