Help identifying a diode

[Dusty_Lenses]

I got a few surplus diodes on ebay that look to be the osram single mode blues that
have numbers on the side of the can:

7H
D8

A pic (attached) from a post from dtr shows "batch 2". Anybody know if the didoes I have may be from a similar production time,
or perhaps a model other than a PL450b? Im not sure if anyone has an idea of , or have decoded the numbering
system etc

The specs ive tested so far is approx 50-60mA threshold producing around 330mW @ 350mA with a vf of 6.5v.
They are also the 3.8mm package type, and appear to redshift when overdriven.

This is the pic I mentioned in reference:

BUMP..
Someone please help Dusty Lenses..

Dusty, why not message DTR as he's been posting alot lately..
If you already did my mistake..

Not to worry, if anyone replies or not im good either way.

I did some further testing and hit 430mW at 400mA, so I think its safe to say
its a newer diode than the older dtr threads I went through from 2015 or so.
I was worried they may be the older ver that arent prone to redshift or
higher outputs, but that doesnt appear to be the case.
