Help with injector nozzel ID

[RMalone]

I have a set of 04. 5 nozzels and I was wondering if any of you gents could help me ID them. The markings are as follows,



EST star(the symbol)F. B. - this part is circled



after that it shows BSLA124P1309 SPRINT.



Any ideas? I was told they had all five holes at . 008. That is about all I know, oh yeah they came in a box that did not say Bosch anywhere on it, from someone named John. :-laf

Okay I figured out that they are 1309 Bosio injectors. Now then, does anyone have any thoughts on these injectors? When I ran them before my injector troubles I thought they were excellent. I swapped out all six injectors tips and all, trying to trouble shoot my rail pressure problems, but I am considering putting those Bosio's on the six injectors currently in the truck. I just hope the problem I had was in the injector bodies and not the nozzels!!
