Without seeing a picture, odds are about 99% that you have a Browning Automatic 5, or more commonly known as an A-5. The gold trigger does not indicate a "Gold" model - hell, Browning has splashed those gaudy triggers over nearly all of their guns for years.
These are excellent shotguns - as good as it gets. You have an FN built gun.
The A-5 is a recoil operated semi-auto shotgun. Try pushing the barrel toward the receiver - it will telescope into the receiver.
"Special Steel" DOES NOT[u/] mean the barrel is a steel shot barrel.
S/N 69V 228xx range is for 1969 production; 69 is the production year, V indicates a magnum model (3 inch chamber). This numbering scheme was used to at least 1976 - I don't know if the current custom shop guns still follow this convention.
I recommend against shooting steel shot in this barrel, but Browning might give it an okay - give them a call. You can always get a new barrel to use with steel shot and save the original barrel for lead - I'm not so sure shooting waterfowl is a good idea with this gun anyway.
You can shoot up to 3 inch long shells in this shotgun; you can also shoot a shorter shell.
If you take the handguard off, the original paper that shows how to install the recoil bushing for magnum or low brass shells may still be intact. If the paper is missing, get a copy of the shotgun's manual from the Browning web site - if you try to shoot a low velocity, light load with the bushing installed in the magnum position, the action will not function in auto-load mode.
The choke codes - look on the the rear left side of the barrel for one or more asterisks and other characters -
* : full choke
*_ : improved modified choke
** : modified
**_ : improved cylinder choke
**$ : skeet
*** : cylinder bore
Hell yes it is a good reliable gun - have fun, and give your folks an extra hug for such an excellent gift.
