Help identify thease INJECTORS

They are stainless injectors and came off a 94 grand cherokee V8. They say 21 lb/hr right on them. They also have a couple numbers that apear as part numbers, 0498 and 01D109B What brand are they and are they any good for anything?

Stan Weiss's big list of fuel injectors

http://users.erols.com/srweiss/tableifc.htm

shows
PN 53030343
as a Jeep 4L injector
with a rating of 21 lbs/hr at 39 psi
and says it has tan colored plastic

Searching the Weiss webpage gives
Delphi 171 0498 8
when 0498 is the search term
but this is a 75 lb/hr injector at 43.5 psi

my memory is fuzzy
but something in my gut tells me that

01D109B

"looks like" a Lucas fuel injector part number,
they have a
01D075B
for example

WitchHunter Performance has a page that lists that Lucas number and has a picture:
