I don't know about the Rodenstock, but I've had excellent results

with an Ilex 229mm barrel lens on my 8x10. Its coated and CHEAP.

Photographic Systems in Albaquerrr Alboquerrr that city in New

Mexico has them, I think it goes for around $70. Good luck and Happy

New Year to everyone!

Are you going to be showing your transparencies on location? If not,

you might try finding an old Elwood 8x10 enlarger. The model I have

pivots so you can project horizontally. They usually sell for a

couple of hundred dollars or less. It might be fun to rig a filter

holder on one so you can make big-big cibachromes. Photographic

systems has Ilex 229mm barrel lens on sale ---I think they're around

$40-70. Mine works fine as an enlarging lens , I wonder how it would

do for projecting trannys? This set up might make an intersting

option for you. Way to ponderous to cart around for presentations,

though!

Verrry interesting! A few nights ago I went through an old cardboard

box of photos, some dating from the 1890's but most from the 1920's

and 30's. The box was stored under the worse conditions possible--in

the rafters of a leaky garage for the last forty years and in a

basement before that. Attic temperatures reach 140 easily here in

the summertime. The photos, nearly all professionally shot and

printed, were in interesting shape. The ones scotch taped to albums

faired the worst. The photoalbum paper itself had discolored and

become very brittle. The photos in the best condition were mounted

and looked very similar to the drymount common today. In fact some

looked like they could have been printed last week. If you could

find what kind of process and materials they used back in the 1920's

you might have an answer to your question. By the way, there was a

stack of celluloid 8x10 negatives that had melted together and had

become highly unstable! Aside from that bit of excitement, it was an

interesting education seeing first hand what stuff like mucilage,

rubber cement and album corners can do to vintage photographs. The

mounted photos were the best preserved,but who knows how they did it?
