I have 5 M3 grease gun mags from maker Sparks Withington
They are all marked SPW GL C 153427
These are for the 45 acp and hold 30 rounds as far as I know
I have NOT tested these for function as I don't have anything to try them on
All are used with minimal wear rust etc
$135 shipped for the lot
Please know your state law when purchasing
Payment by USPS MO or Personal Check preferred
PM me with any questions
Thanks
Marcel
