According to bluebookofpianos.com, an Acrosonic piano with this serial number would have been manufactured in 1964.
That serial number would put it as an Official Police made in 1968
No way to tell. Contrary to popular belief, a serial number is not unique to only one gun in the world. If it were, the serial number would have digits into the billions.
I do not believe the model 325's were manufactured after 1968. Therefore they required no serial number and yours may not have one. If it did have a serial number it would be on the receiver.
Records would indicate it was manufactured in1942.
With this serial number it would have been made in 1926. If there is a letter above or preceding this number it would change the date.
A 40 hp Mercury outboard, serial number 5897057, would have been manufactured in late 1981.
I think the only Winchester with a serial number that high would be a Model 94 manufactured in 1972.
1971
I would guess about 1980....................
It would have to be sometime after 1978 as proofhouse.com lists Colt combat commander ending in 1978 with a serial number beginning 70SC57900
That would be 1977. 1978 Since 1977 started with serial number 70SC50201 and 1978 started with serial number 70SC57900 and the Commander in question is serial number 70SC57072, it would have to been manufactured in the latter part of 1977.per proofhouse.com
