MBK Mirage HPF?
 

Anyone familiar with the MBK HPF frame from the 90s? Love the shape, but....aparently is not a popular bike.

What HPF means and what steel is used?

Thank you!

HPF is a dupont material maybe?

no idea what the HPF means (though there seems to be something on the seat tube that might start with "CHR" maybe for chrom-moly?) but do know that the brand MBK is what Motobecane morphed into. Probably a nice French frame, looks like TiG welding and a pretty radical low fastback stay treatment.
How about a few close-ups of the details?

Sorry, dont have close-up pictures, thats why i wont to know more.

Well, i bought it! Looks ok,
