Hello, new member here, got a question

"The only markings on the barrel are as follows and in order:
B o 3 1
1801 ( matching ser #)
a ( small cursive)
388( or 333 or 383 or 888 or some variation of"

It sounds like a 1914 with a B�¶hler barrel in 9mm (8,83 bore gauge), that has been relined to 7.65 mm /.30 Luger.
