I think Raimey has it right. This gun doesn't seem to be a Lindner gun. He points out that "The forend bump is different as are the "church windows" Also;
The frame is not the same as the second series of Lindner guns. The screw pattern is different.
The gun has a dolls head instead of rib extenstion.
The engraving is similar but clearly different.
The area around the cocking indicators is stippled.
The thru lug is square instead of rectangular.
The trigger guard and top lever are blued instead case colored.
The side clips are more pronounced on Lindner guns.
It'd hard to tell from the pictures but if this the gun from G&H, it is listed as having ejecters, but this gun seems NOT to have the distinctive Lindner ejector "eyes" in the forearm.
Having said all that, it looks like a very nice example of a post WW1 Daly, just not a Lindner made gun.
Could you post the serial number?
Best,
Jon
