Yep. I'm pretty sure I weighed a kit a few years ago and it used 5 grams of glycin.

Lowe discussed many of the mainstream and off-beat formulas in his "(What you should know about) DEVELOPERS Fine Grain and Otherwise", Camera Craft, 1939. Ansel Adams used it as a reference work in his first series of text books. Two Champlin formulas were evaluated, 15 & 16. Champlin's approach was discussed in Lowe's sympathetic and calm manner, "Some of the chemical theories expounded are rather unorthodox, and the author states a number of his own opinions as if they were proven facts. This, together with some unusually optimistic claims as to the merits of the Champlin formulas, has tended to discredit Mr. Champlin's among serious photographers."

Champlin's work, however exciting his writing and our own eagerness to believe, tends to not stand up to 21st century standards. Not surprising, many of our APUG contributors have better labs than Champlin, Harvey,and many others could have dreamt of. Perversely, the best work of the pre-war era seems to have been overlooked, while the sketchy, dodgy, and bizarre has survived.
Anybody else have Lowe's book ?

Well said. Your formula for E-10 jogged my memory a bit and I found a copy of it in my filing stash. This formula, from darkroompro.com, calls for:
all others the same
What made me think about this dev was the dev time of 1 hour, yes, 1 hour at a 1+10 dilution!
I'll try to find the link.
Sorry, link is no more.
DF, do you have times & dilutions for E-10?

I think a starting place would be to dilute E10 1+3
and develop as if it were D-76H 1+1.
Edwal 10 1+3
What do you think ?
I KNOW it won't blow up !
(will it ?)
Thanks. Last I knew, D-76H times were the same as D-76, so I'll use those.
It's only film and were all so rich these days...
If you don't here from me again, it blew up.
I have been meaning to acquire a copy of that book for the better part of eighteen months...

I should add that your reduced agitation techniques have proved very useful, and work brilliantly well with both Rodinal and Aculux 3.
I will update this when I locate a copy of Lowe's book!
P.S. I did a quick COPAC search (all the academic libraries in the UK) and it turned up a lone copy in the National Library of Scotland.

Watcha up to ?
Those agitation techniques aren't mine... but a bunch of real old timers would be happy they work for you !
Here are my film development times for well seasoned edwal 12, 75 degrees
3 inversions to start then 1 inversion every 30 seconds:
Tmax 100 rated 125 5.5 mints
Tmax 400 rated 400 6.5 mints
TriX rated 650 4.5 mints
Neopan 400 rated 400 4.5 mints
Forma Action Pan 400 rated 320 5 mints.
