Help identifying pistons

[Dustin2000deuce]

I havea 2000 softail deuce, has branch and O'Keefe 95ci flow metric kit , the pistons are stamped J&E 97m , but no serial or part number  . I've attempted to contact branch to no avail, I've seen a lot of pistons on a lot of different pages but I can't find this unique shape of the dome top I don't know if it's one off or a specific name or any ideas or help would be appreciated thanks y'all.You cannot see attachments on this board.

looks like 22571-07 (113" 10.5:1pistons, when used with CVO 110 or 110+ heads) or 22137-08 (110 10.5:1 with CVO heads or 110+ heads)
Found in a 2008 SE catalog, page 50.

Branch welds up the chambers & cuts them to that shape. The piston # might be theirs.

Contact JE Pistons. Give them the info, including that they were used with Branch heads (year, cu. in. and model). they should be able to give you the info. The sheet should look like this one. These were pistons I designed for turbo-charged Twin Cams when they first came out.

The S&S pistons for the 97 or 98 3.928 and 3.938 domes are very close and will work verified by clay checking with .040 head gasket.
