My guess is 1917-1919. I know it's not 1916, and I think 1920 had a reinforced neck. Of course Mark Masa will know.

It’s a 1921 to mid 1923 frame.

If that short tank mounting strip on the top tube aft of the seat T mount is original, just take a wire brush to it. The two digit year is stamped into it.

Mark is the man on Js., but didn't the 920 frame have a neck reinforcement addition.

So i guess the frame is a 1923. Holy Sh_T, the JD motor i purchased separately is a 1923. Now that my rebuilder has finally found the time to do up my Motor, i'm shooting for 2022 Wauseon 1/2 mile Board Track Class.
Thank you Guys for your efforts! You need to write that J/JD book Mr. Masa.

Eric
it does have the reinforced neck but it’s hard to see in the pics.

Dear All, the JD book will be out next month, put together by me with the help of 25 other AMCA members.
