To determine the year of a champion blue ribbon boat motor with the serial number 4K307004, you typically need to refer to the manufacturer's specific serial number lookup or database. Generally, the first letter or digit can indicate the year of manufacture, but without more context or access to those resources, I can't provide the exact year. You may want to contact the manufacturer or check their website for detailed information regarding serial numbers.
The Iver Johnson 12 gauge Champion shotgun with serial number 70369 was likely manufactured around 1922. Iver Johnson's Champion models were produced primarily from the early 1900s until the late 1930s, and specific serial number ranges can help narrow down the production date. For the most accurate dating, consulting a detailed Iver Johnson serial number reference guide would be beneficial.

Probably isn't one if it was manufactured before 1969. I think the Champion was still manufactured into the 1970s. If so, the last ones were required to have a serial number clearly marked on the receiver.

The Champion 410, a shotgun model produced by the Champion Arms Company, was primarily manufactured in the 1980s.

If you have a specific serial number, you might be able to identify its exact manufacturing date through resources or databases specific to firearm serial numbers.
No more than 100 USD, if that.
