Got an answer from the importers.
The Ejectors are held in place by the Ejector Trips, these run vertically up and into a slot on the ejectors.
On the ejector trip is a very small pip with a hole in it, underneath this hole there is a small plunger and coil spring (this keeps the ejector trip in place, not allowing the ejector trip to drop down). To remove the ejector you need to have a small pin punch that you place into the hole of the pip. The process of removing the ejector is as follows, keeping the ejector held into the barrel, insert pin punch into pip hole (depressing the plunger and coil spring), pull the ejector trip very slightly downwards. Releasing the ejector it should now slide out. When replacing the ejector all you need to do is push ejector back into barrel and at the same time push ejector trip upwards locking ejector and ejector trip in place.
Vacuum is generated by using Ejectors. 1. steam jet ejectors 2. water jet ejectors. may be single, double or 3 effect.
Incondensible gases, are gases that do not condense and do not dissolve readily in hot water. Steam ejectors are used to remove these gases from a condenser.
You must contact the maker for a correct answer.
I have a 20 o/u and it doesn't have auto ejectors..... doubt if the 12 does.
example serial number: 13-03-01304-09-12-76 13 is the maker (in this case Lanber) 03 type of gun (shotgun) 01304 is serial # 09 is the year of manufacture 12 is the caliber 76 is the length mm
100-400 USD
About $225-$300, depending on condition.
Lanber 2087's are being sold as of 9/22/07 by www.cdnninvestments.com (then downloard the catalog) in catalog 2007-5 for $599.00 retail. They have sold 2085's in the past, you might give them a call. Commentary: I own a Lanber Model 87 and it is a terrific gun for the money. Beyond the measure of money it is still a very nice gun. Spanish manufacture and CDNN claims they are the OEM for some Weatherby Shotguns.... Hope that helps. Mike
Excel Arms of America, Gardner, MA., was an importer of guns made by Lanber, Laurona and Ugartechia and ceased importing during 1967. It is unlikely to find enough current sales of your model to get an accurate value. All 3 makers were in Spain, and only Lanber is still in production. A Lanber O/U retails for $450-$700 or so .

By gravity / forced main which rely on pumps AKA sewerage ejectors
