How do i add the mohawk pistol into my wad?

[Shakariki Heisenberg]

I'm currently facing difficulties extracting the Dehacked states and related information for the pistol in Mohawk2.
I'm not sure if the pistol is from another mod or if it was created by someone involved in the project, but it's a high-quality addition.
If manage to overcome these hurdles and successfully integrate it into my project,
I am committed to giving proper credit to the creator.
To ensure clarity, I kindly request assistance in confirming whether this particular thread
is the appropriate venue for seeking guidance and resolving the extraction issue.
Your guidance and support would be greatly appreciated.
