    You guys forget "chains", "stones" and "furlongs" for starters.

    In school, we had to calculate the speed of light in furlongs per fortnight!

    Oh, and there is a French measurement that translates to "horse gas hours" which is probably like horsepower in Englis.

    One hour of horse gas is probably one too many.

    And all these things made perfectly good sense at the time they were the standard.

    Let's take a moment to thank our French cousins for freeing us from the Imperial baloney we once relied on.

    i see, that's actually funny. my mistake, but 1 milliliter is .00022 of an imperial gallon, not .0022.

    so there are approximately 4546.092 milliliters in an imperial gallon, just in case anyone really wants to know.

    Can anyone give me an idea what this might be worth? Also how do I tell the age of the paper?

    Thanks for your help!

    great find gordon !

    i see you do pinhole work, this paper is very slow ( silver chloride used to be called "gaslight paper" by some )
    it requires like a 300W flood light and dense +contrasty film works the best, so using it in a pinhole camera might not be useful.

    if you have a box camera ... you could expose your film, and process it in dilute dektol
    for a little longer than you might normally ( if you ever normally processed film in it it used to be suggested 7 min / 1: 7 )
    to build up density and contrast ...
    cut your film down and make contact prints ...

    you might consider paper negatives make with a camera of some sort
    to make contact prints on your paper.

    i love making photograms on azo i have

    good luck ( and have fun )

    ps.

    my car gets 40 rods to the hogshead ...

    I don't remember exactly, but it seems to me Kodak began the move from packages of 12 and 144, to 10, 25, and 100 around 1950-1955. Agfa and others followed along soon after.
    I have always thought it ridiculous to sell sheet film in boxes of 25 which means one can load 12 holders and have a sheet left over in the box. Paper was boxed in the same quantities as film.

    If you really want to get confused on old measurement systems get stuck in looking at old English systems for acres, townships, etc
    And, try the old English units for money used up until 1971, Pounds, Shillings and Pence.
    12 penny's in a Shilling, 20 Shillings in a Pound.
