What year is my savage 30-06 model 110 serial number F979072

. The "dating" service is intended more for dating and documenting the older collectable guns that are no longer in production and were made prior to 1980.

"F" prefix with a serial number lower than F498821 = 1989 thru Nov. 1st, 1995
"F" prefix with a serial number higher than F498821 = Nov. 1st, 1995 through the end of 2002
"G" prefix started in 2003 with the introduction of the AccuTrigger
"H" prefix started in January of 2010

Singer model 99

Did you leave off any letters in the serial number? The 5,755,498 serial number would have been issued/built in 1883. However, Singer records don't give a model number for machines built before 1900. You can find a series of look up tables for Singer serial numbers here: . The tables are organized by the prefix (or lack of a prefix).

I hope this helps.

Looking for a heater / a/c climate controle switch for a 89 ford tempo, all local stores wont carry and when im online it says the part never existed, so i guess i need the actual name and ford pa

Sometimes you have to bite the bullet and go to the Dealer. The Dealer has a book called an OSI book. Obsolete, Superceded, and Interchange are the way it is organized.

For used parts try For a better understanding of Ford parts-they carry 2 types of part numbers. There is a Service number and an Engineering number.

The Service number is the over-the counter part number. The part numbers have a middle BASE number and the numbers and letters before the BASE number are Prefixes. The Prefix tells the Year and Model of vehicle. If a part is a D8AZ it is for a 1978 full size Ford, a D9 is for a 1979 full size. A D8MY is for a full size Mercury, D8LY is for a Lincoln.

These first numbers can be important, but if they interchange there are 2 things to know. A Ford part is usually cheaper than a Lincoln part and you can't go by the Prefix. That is why the BASE number is referenced. This is not to say the Suffix is not important, as the suffix can notate Engineering changes when looking at an Engineering number.

For instance, The first run part has an "A" Engineering suffix. Improvements could end with "B" or "AA". Perhaps the "A" suffix fits only the Mercury, but a modified "B" or "AA" could fit both Mercury and Ford sister cars.

This is why you need to know what each part of the Engineering number means.or have the Service number. Ford usually stamps or labels, or moulds only the engineering number on components.

What year is this Triumph engine # TR5 H18931

Let's start to narrow it down.

From the number, it was made AFTER 1945 (when they started to feature a model code before the serial number), but before 1969 (Triumph changed its serial numbering system to include a two-letter prefix to denote month and year of manufacture, followed by model code and serial number).

The "H" denotes that it is a 500 twin model.

The 1961 production run ran from H18612 toH25251.
Your number falls into this range, so yes, it's a 1961, 500 cc engine, and the model of bike it came off of is called a "Trophy 500".

Hi "merleneff"

The serial number on the engine is totally different from the VIN number on the frame. If you had the VIN number from the frame, I could give you all the details.

The only info you can get from your engine number is the production date and origin of manufacture. You can call the Yamaha Motorcycle Corporation for this info.

Hope this helps you out!

You will need the prefix to find more info, the engine size is usually cast into the barrel at the rear
