Gallienus left bust from Milan

Hello!
I bought some days ago this piece of Gallienus from Milan mint (the style is "milanese"):




D\ GALLIENVS AVG
R\ PROVIDENTIA(?) AVG / M(?)

Could it be another specimen of this one?

Many thanks!

The above pictured coin looks like MIR 1086 i (divergent ribbons) rather than a possible MIR 1086 o (parallel ribbons). Moreover it could have an obverse and a reverse die link to the coin MIR 1086 i pictured on MIR Tafel 86.

Thans.
During these days I am out of home so I have not the MIR... how many specimens are listed for 1086-i?

8 specimens listed in MIR under 1086 i.

Thanks, so it is a not so common piece!
