Brownie Target Six-20

mhcfires
I just acquired a Brownie Target Six-20 from collectiblecameras.com. I am fascinated by this old and unassuming device. I need another 620 spool before I respool 120 and shoot it. Sounds tedious. Where do all of you find your treasures? I didn't know there was a portrait model until I came here. I'd like to get one.

Do you get good results with 25 or 50 speed film? What do you (or anyone) suggest for my first roll of B&W?
Does anyone know what the apertures and / or shutter speed is (besides B)?

I have successfully used Delta 100, Tri-X 400 in my Target 620. If you need a spool, PM me your address and email and I can send you one. No problem. I posted a shot taken in Jerome, AZ in October, 2008. It was taken in early afternoon. I think it was on Delta 100, can't remember for sure.

Here are links to a few more taken with this little camera:
