Serial NO. 110530 model 1917 .45 what year was it manufactured ?

1964
Winchester model 70s in 1964 started with sn 700, one has been fired but need to 36699. 06, 12 serial number 1 - 20 guage for models which have a 5 digit serial number can anyone tell me what year. Date manufactured in advance, made a pre-64 model 70 is this ramp because of manufacture by serial numbers prior.Feb 5, 2019

On Marlin-branded Model 60 rifles, the first two digits of the serial number indicate the year of manufacture. For example, if the serial number starts with 18... The 18 is significant, for subtracting it from 2000 gives the date of manufacture for the rifle, 1982. Likewise, a serial number starting with 17 would be a rifle manufactured in 1983.

This method has not been uniformly followed. It is valid only from 1971 through 1999. Prior to 1971, the first two digits indicated the year of manufacture. For example, a rifle with a serial number starting with 70... would have been made in 1970. Starting in 2000, this same old method has returned; the first two digits once more indicate the year of manufacture directly, with no subtraction required.

very few serial numbers give indication of year of manufacture
a year of manufacture will show when a serial number began but will not tell how many years variations of that serial number ran for
for example in 1990 a serial number 0010101 was started for the first item produced but after 10 years the serial number will be 00101999 so 001011596 will not show a year of manufacture just that it was produced between 1990 and 2000
to add more confusion
in your particular question example a model 7800576 could have been produced in 3 different countries and the serial number will be from any one of those countries as each set of serial numbers will denote which country it was made in
may be it you contacted the manufacturer technical division, they may be able to provide a matrix that will answer your question better

Nope. Model 1895 ended with serial number 425825 in 1932. Check out the PDF for models and serial numbers.

The date of manufacture is determined by the SERIAL NUMBER on the appliance. This dishwasher was manufactured by Whirlpool. The following link explains how to determine when it was manufactured:

The serial number is usually located somewhere around the door opening. The first two numbers in the serial number identify the WEEK it was manufactured (52 weeks in a year). The second DIGIT in the serial represents the YEAR it was manufactured.

If you have difficulty determining the manufacture date, please post back with your serial number and I will assist you. I hope you find this information helpful.
