Anyone have a black diamond drill grinder?

[Rusty Hobs]

I recently joined this forum and I am trying to aquire some metal working tools. I purchased an old Black Diamond drill grinder and unfortunately it is mssing some parts. Does anyone have a grinder that they can send a picture or two showing how it is setup? I believe, I am missing the part that holds the drill. I have some of the collets but nothing to hold them.

Thanks,

Thanks Paddy.
I have a model 2A. Between your picture and some on Eb, I located a couple of the missing parts in with some other parts that I bought. I think that I am still missing the collet holder. I have about 20 collets but nothing to hold them. I located the small hand wheel that tightens the collet holder.

I found a vendor selling a manual. When it gets here I will have a better idea of what else I am missing. My grinder had been sitting on a shelf for 10 years and is quite rusty. It will be a project. The motor works and I have a new wheel. BTW, what is the purpose of the step in the wheel?
Thanks for your help.
