The serial number 45987 does not show in any of my sources. There is one source, Proofhouse.com, which states that before 1958, Browning serial numbers did not contain date or model information, and cannot be dated using the serial number.
I would further ask, does your gun actually state 'Hi-Power'?
John Moses Browning designed this gun, as well as many others such as the Colt Government 1911, but sold the designs or had them made by other companies.
FN made most of his guns and FN finally purchased the company in 1977.
You will experience trials and tribulations, arguably more dating warwick ny than other couples since you may never understand exactly what he has experienced.

The serial number on the grip frame is: Z10017* The serial number on the barrel shroud is the same but lacks the "Z" Thanks!Upon introduction in 1959m all rifles were produced by FN in Belgium. Sako also provided barrek=led actions in the small action (L461). Note that Sako was the only manufactureer that could stand up to the FN requirements. The medallion and Olympian Grades followed in 1960. These were made in Japan starting in 1977 to replace the Belgian Rifles. In 1983 there was a Limited Edition of 1000 rifles. the Browning long FN actions were prefixed (suffixed) with an L. The Safari Grade was the first of the line in 1959.
