Default SMD trimmer resistor old alphanumeric markings?

I have some older SMD trimmer resistors (late '90's) that have 2-character alphanumeric markings.

This format doesn't seem to be a practice used by current brands.

For example, I have some marked Y 3. Sample of 1 measured 3.3k.
'Normal' marking one could read might be 303 or 3 3 if I concluded that was probsbly a 3 k 10 or 20% part.

Does this ring a bell for anyone? 3.9 mm x 3.1 mm x 1.4 mm, open kind of construction, slotted metal rotator which is connected to wiper also (not insulated!).

I went through Digikey & Mouser catalog links...

Yeah, I can just measure them but I don't want to give up that easily. There is trivial info to be found!

Thanks
