A new Claudius II reverse type ?

Hello!
I have just bought this coin of Claudius II




D/ IMP C CLAVDIVS AVG
R/ FIDES EXERCITI, no mintmark

It seems to be a 1st issue from Rome mint probably from 11 officina as the common short type legend reverse "FIDES EXERCI" listed at n. 274 of new RIC http://www.ric.mom.fr/en/coin/274?q=274&page=1&mod=result&x=0&y=0&from=quick

Is it actually a new type or did I get my search wrong?

Probably a new type (may be an early one with a longer reverse legend more difficult to place than the common shorter one used with both GENIVS and FIDES). Not in the recently published Saint Germain lès Arpajon and Beau Street Bath hoards.

Many thanks AMICTVS!
