This question is impossible to answer without knowing the type of firearm and its condition. Several types of gun were made for Charles Daly by the Japanese. Take the gun to a gunsmith and have it identified as to model and condition before resubmitting this question.
The firm B.C. Miroku of Tokyo, Japan made the Charles Daly name of over and under shotguns from 1963 to 1976. Not a lot is known about this firearm, as retaining data apparently was not thought important when they were being sold. This shotgun has a value of around $700.
Miroku guns made under their name does not have serial info published. Winchester, Charles Daly and Browning have all been made by Miroku in the past. Do you have a model?
The exact value of a Charles Daly Italian Diamond Trap firearm would actually be dependent upon a number of factors. Some of these factors would be the condition and age of the firearm.
You will have to contact Miroku to find out.
Miroku was making shotguns for different firearms Companies before Browning came along. Charles Daly was one of their biggest customers for shotguns. More info is needed to determine which gun you have. This is not a Browning serial number.
Possibly if it is a Browning made by Miroku.
You will have to contact Miroku
The letters NZ in the serial number indicate that your Miroku made Browning was made in the year 1991.
Sorry- no public records. You can try contacting Miroku.
In like "new condition", expect to pay around $1000 in a retail store.
No way to tell from the sn. You will have to contact Miroku
