I've acquired a mint Ansco 8x10 camera with six new Lisco holders. The camera includes a Protar VII Triple convertible lens. I've never shot with anything but current Schneiders etc.
The front element is a 23 1/4" and the rear is a 18 7/8".
The faceplate on the No.5 Universal Shutter shows the f/stop scales for the 23, 18 and the combined (I assume) focal length of 12"
Question is, if I only use one element such as the 18 7/8", do you always put it on the front of the lens so the shutter isn't exposed to the air or do either always go on the rear?
Secondly, if I do use them both as a 12" lens, does the higher element always go in front or does it matter?
Also, the highest speed is 1/50 sec and my shutter checker says it is slow at 1/25 sec. Does anyone have a favorite shutter repairman they would suggest?
Just got the box of film and heading to the coast this weekend.
Thanks for the help.
