I see what you're saying, but hte greeks could be refurbs. I've had TWO 1950 LB's, both 95L's and both with factory blue on every part. Of course, they could be aberrations. One had an RSAF Enfield front handguard and was ENGLAND stamped (re-import) and the other came slathere in cosmo from a gunshow - likely unissued. Sadly, both have been sold off a few years agoI did have pics, but lost them in a HDD crash
The 15 or so rifles in your survey are hardly representative IMHO as with that small a sample most might be refurbs - who knows?
Everything I've ever read in books (as oposed to forums) indicates the switch to park happened AFTER 1950 at CAL.
