Any Ideas On What Nib This Platinum Ptl-5000A Has?

[Intensity]

I have been trying to find some comparative images of Platinum's PTL series nibs to figure out if this is a fine, medium, etc. but no luck so far.

 

Here's the seller's photograph of the nib:

 

 

I realize the two small characters at the base of the nib are difficult to read, but perhaps it's still obvious to someone what this nib should be.

 

Thank you!

 

Update: I believe it's an Extra Fine. Reasonably confident in that now.

Can't really help -- my pair of PTL5000A pens are marked

 

14K M

14K EF

 

My Carbon desk pens have a single glyph on the M (sort of a rectangle [=] with a | down the center), and the EF has some complex two grouping markings (on an angle, the first grouping almost looked like "fox" <G>, the second has a "house" followed by a four-pane window shape)

Thank you, that goes along with my guess of this nib being EF.

They read 極細, meaning (for) extremely tiny (writing), so in terms of nib grades, it's an Extra Fine.
