300mm enlarging lens

[Jerry Cunningham]

Sir:
I recently purchased a Rodenstock Rodagon 300mm F1:5.6 lens. I hope to use the lens in an 8x10 enlarger. I have several questions.
1. The lens appears to be coated. If that is true is this a single or a multi coated lens?
2. Is this an six element lens?
3. It appears to have a thread pitch of 72mm. Is that true and if so where could I go to purchase one?
Thanks in advance
Jerry Cunningham

Cheers, Bob.
