Looks fine. Some large(r) Puro and Puro 'made fors' still use the assembly string including the FL 1A. Seems confirmed with google image search, and this one relatively new. As long as no functional effect as here, no problem. Never figured out why the FL 1A specs nitrile adbv as opposed to majority MCs using silicone. Perhaps has to do with filter orientation in models used?
Thanks for c&p. Nice ride btw.
