First your serial number indicates that your Winchester model 62 was made in the year 1942.The model 62 was never produced by Winchester with a Nickel plated finish from the factory.These gallery guns were used through out the country at circus,s and thats where the term gallery gun comes from(shooting galleries).at some point in time a circus owner or private individual had your model 62 nickel plated.
I can tell you that by your serial number your Winchester model 1906 rifle was made in the year 1919. I can also say that this model was made from 1906-1935,with a total production figure of 731,852.I must say Bert that I am not aware of any nickel plated parts for the model 1906,but that does not mean that they were not made.They also could have been Nickel plated at any time after production also.
Depending on condition, $275-$375.
Your Winchester model 290 ranges in price from 90-200 dollars based on overall condition.
The value of a Savage Arms Corp 12 gauge model number 775A nickel plated gun depends on its condition. This gun in excellent condition is valued between 150.00 and 175.00 as of 2014.
I have a serial # 546136 B it was produced in 1919 One in refinished condition with a peep sight sold for $1,265 I suppose it depends on the condition for a price
Depending on model and exact condition, $150-$200
probably some time after it was made. the military model was not nickel plated.
