<p>Hey guys,<br /> I just purchased a Speed Graphic off eBay. I fired the shutter a few times and everything seemed to be working. I then flicked the BACK/FRONT switch to FRONT and then back to BACK and now I'm noticing that the focal plane shutter won't reset past "T". I tried increasing the tension but it seems like there's a hard stop before "O". The shutter is stuck closed. All the other speeds seem to work okay. If I hold the shutter button and wind the shutter forward, the top roller just creates slack in the shutter. Does anyone know anything about this issue? Any help would be greatly appreciated!<br /> Thanks,<br /> John</p>
