Question on 1919 internal parts value

Not sure if this is the right place to ask but,
I have internal 1919 semi auto internals surplus to my needs. They are machined and ready to go, never been used since machining. They are izzy parts. I have no idea what the value is. I also have internals for auto also that are surplus to my needs (same parts as in pic). Any idea what the going value is?

thanks

Down here semi bolts run around $225, barrel extension $75, lock frame $185.

Thanks, that helps :D
