Thank you very much Beretta for a great offer, I appreciate it! As well thanks to every body else who posted , great community here !!!
But I think I was able to locate the choke markings on the gun, thanks to REM !
* Full on the top and
** modified on the bottom barrel,
dime sits on end on the front of the barrel. It just sits and does not drop in.
The serial number is 27591 S73.
Not sure what salt wood is or how to check for it.
Here are more pictures as requested.
Many Thanks again to all !!!
Here is a good description of the salt wood issue not my words
The best discussion of the Browning salt wood issue is in Ned
Schwing's "Browning Superposed" book (Krause Press, 1996). According
to Schwing, in the mid '60s Browning needed a better supply of high
grade walnut for it's guns. A California contractor had a large
inventory of good walnut taken from clearing power line right of ways.
Demand for Browning guns was at an all time high and the usual kiln
drying process for walnut was too slow to produce what was needed.
Rapid kiln drying also produced cracks in the California walnut.
Morton Salt had developed a salt solution drying process successfully
used in the furniture industry with good results. This cured the
walnut much faster than the kiln method. Browning tested it and there
were no problems, so Browning bought the process in 1965. "In an area
roughly the size of a football field, five-foot by five-foot by
eight-foot stacks of stock blanks were covered with salt. The salt was
supposed to leach out the moisture and dry the wood quickly. The
process did accomplish its purpose but the moisture that was drawn out
of the blanks on top of the stacks ran down into the blanks below,
resulting in a brine solution that soaked the lower wood blanks."
(Schwing, pp 246) The retained salt reacted with the gun metal with
the finished stock was installed. This caused the rust associated with
"the salt wood problem".
According to Schwing's interviews with Browning's Harm Williams and
Val Browning, all the salt curing was done in the US and affected at
least 90% of all Browning stocks from made from 1967 to 1969. The
problem continued to show up until 1972, but in smaller numbers. It
was then that the entire supply of walnut blanks was burned and
replaced with traditional kiln dried wood.
To detect salt wood on 1966 to 1972 guns, first check for outward
appearance of dark or discolored spots. Check every place that wood
meets metal, as on the rear of the forend and at the head of the
stock. Rust on the metal will be apparent if there is a problem.
According to Schwing, the definitive test is to remove the butt
pad/plate, scrape away a little wood from the exposed butt and apply a
1% solution of silver nitrate to the fresh wood. If the silver nitrate
remains light purple, there is no salt. If the silver nitrate turns
white, you have a salt gun.
If you can prove that you are the original owner of the salt gun,
Browning used to replace the wood for free and will probably still do
so. If you bought the gun used, you are on your own. I got a used
Superposed 410 with salt wood about ten or twelve years ago. Browning
charged me about $250, if memory serves, to replace the wood. It
wasn't free, but it was certainly a bargain price. I don't know what
the numbers today are.
By the way, Browning wasn't the only one to get taken in by the salt
wood walnut curing process. I've heard that some other gun companies
did also, but weren't quite as up front about dealing with it.
Unfortunately regardless the year of your gun it has to be checked since it is too close and more important since Art Isaacson (Art's Gun Shop) has documented many times that salt wood superposed guns have S7, S8 or S9 in their serial numbers. No body knows more about this problem or did more warranty work as a result of this than he did . Google is name if you want to check him out
All that being said IMO from looking at the pics of the gun I think the original owner had the wood changed out under warranty but one has to be sure
Sorry but just sharing the little bit I know about this
Also just to add if you were the original owner and it was a salt gun browning as far as I know will still deal with it. Here is one case from 2012 from a member on another forum. Nice offer IMO
His words
Browning did not refuse to repair it, said it would take 6 to 8 months or more & would be a lot of work. They offered me the Citori 725 instead of repairing my gun & I had to decide if I wanted the repaired Superposed classic or a new modern gun. I thought that was a fair offer & accepted it. ( It just took them a very long time to find out it's condition)
Cheers
