fiberglass shafts - what are they?

[Oregon Okie]

Hate to be this guy again. Got some fiberglass shafts - no markings. Ring any bells with anyone?

Micro-flites were yellow like that.  Each shaft was marked with the word micro-flite followed by a number, designating the size which corresponded to spine.  Ranged from 0 to 10 initially, and later to 12.  For example, a micro-flite 7 was about 55#@28 inches. Looks like someone might have taken off the identifying information in cleaning them up.

Those look like old Martin Archery A20 glass shafts.

Unusual that they would not be marked.  As Orion said, they look like Micro flite, but with no markings they coulf be something else.

I never kew about Martin A20.

According to my recollection a Microflite 7 was for 45-50#.  I used to shoot 8's out of my 50# and everyone said I was shooting too heavy a shaft.  When I consulted the charts, they were right.  This was back in the late '60's.

I bought a big lot of archery supplies and much of the stuff was Martin so maybe that's another indicator. I need a CSI to find some markings

Trust me those are A20 Martin shafts. They are ot Microflites
