[help] Weapons not spawning

so I have been at this for a little while now, there are certain weapons that I have the spawn names for and everything and they simply do not spawn no matter what i do to spawn them.

I run VORP and i have tried placing them in the weapon stores, I am able to buy the weapon and it appears in my inventory but when i attempt to equip it nothing happens.

I have also tried in a sperate script to just force spawn it directly with the following code again with no success

Citizen.InvokeNative(0xB282DC6EBD803C75, GetPlayerPed(), GetHashKey(“WEAPON_REVOLVER_SCHOFIELD_GOLDEN”), 500, true, 0)

the above snipit uses the golden schofield but this is just one of several weapons that fail to spawn, and I know the above code does work because i have tested it with other weapons.

I have been informed that these weapons do infact work for other servers so i guess my real question here is what am I doing wrong? or is this a known issue with these specific weapons?
