F9815SLN1 is a non-gated variant. Could be both thin-filmed SelA or standard-filmed tube.

minimum assured specs 57 lp/mm, 1350 micA/lm, SNR 16.2, max. EBI 2.5xE-11
typical specs 64 lp/mm and SNR 21.

Spots allowed
none allowed for zone 1
one 0.009–0.012in sized spot in zone 2 or 3
two 0.006–0.009in sized spots in zone 2 or 3
two 0.003–0.006in sized spots in zone 2 or three in zone 3

Although minimum specs are not that great, typically this tube could at least match if not outperform any OMNI V you can find. But performance may vary and I'd expect at least one parameter be a bit off-limits. Thus, a good look through the tube before making a final decision is recommended.

BTW, according to the serial, this tube was made in April 2007.
Any color you like...

No problem, Robert. You are welcome..
:?: Although I think that the only way to determine which one suits you best is simply look through them.
