Thought I would bring this thread back up with a few more pictures (although totally not related to the stalker)...
First a Direct Connect concept pump which came around a little to late. Brass body, pump has guide rail built into frame, and aluminum feed block.
Second is a Palmer's-ish BBT-ish sheridan based pump. Only things Palmer's related on it are the barrel system and the nickel plating. I haven't actually compared it to any of my other palmer's gun with removable barrels. Bottom tube is from some sheridan pump, pump is cooper-t and valve is stock. It doesn't have a palmers detente so i think it might just be from else where. Still a nice looking pump though.
