Need help finding a part number for Marushin ASG STI 1911-A1 Shell Ejecting

[Sebthefen]

Hello!
so i have recently purchased 2 marushin 1911's, and on both of them, the leaf spring has gone, i have contacted a company called Impulse101 who can help me get the part from marushin themselves, however, i need a part number which i was told would be included in the manual, however, i have read through my manual (not too hard, only 5 pages) and theres no part numbers anywhere.
Pictures included are the manual i had recieved with the pistols, and a picture of the leaf spring, i wish i could use a standard 1911 spring, but these ones are slightly different which is quite infuriating
Any help would be appreciated
-Seb
