Help with Scamp VIN

[peterh]

Given that the "-8-" in the sequence is your VIN check-digit, you can do a little math magic and we can calculate the possibilities for the missing digits. (See http://en.wikipedia.org/wiki/Vehicle...ication_Number for details on how VINs are constructed, see http://scamp.n0kfb.org/VIN_Decoding/VIN-Decoding.htm for the coding particulars for Scamp trailers.)

Here are the possibilities:

1S7-R1310-8-C00-10669 for a 1982 Scamp 13 Standard
1S7-R1310-8-G10-10669 for a 1986 Scamp 13 Deluxe (wood interior)
1S7-R1310-8-L00-10669 for a 1990 Scamp 13 Standard

There are additional possibilities in the 90s and 00s, but I did not check them.

Thanks Peter...I'm pretty sure its a 1982 through 1987 from previous conversations, and its not a deluxe, but I cannot figure out how you figured it has a "C" in the VIN for a 1982. Why could the "C" per you, not be a "D" for an 1983, or an "E" or and 1984, and so on?

Thanks again,
Frank

"Checkdigits" are a mathematical tool invented by the credit card industry to reduce the number of times a data-entry person hit the wrong key or transposed two digits while entering a credit card number, and, therefore, reduce the number of times a bill was sent to the wrong credit card customer.

For a VIN, the check-digit calculation works like this:

1) The alphabetic numbers in your trailer VIN are replaced by a number (I,O, and Q are not used because they look like ones and zeros):
A->1, B->2, C->3, D->4, E->5, F->6, G->7, H->8, I->X,
J->1, K->2, L->3, M->4, N->5, O->X, P->7, Q->X, R->9,
S->2, T->3, U->4, V->5, W->6, X->7, Y->8, Z->9

--1--S--7--R--1--3--1--0--8--C--0--0--1--0--6--6--9-- changes to
--1--2--7--9--1--3--1--0--8--3--0--0--1--0--6--6--9--

2) Each of the numbers are multiplied by another number, and those products added together (the check-digit position is multiplied by zero):

--1--2--7--9--1--3--1--0--8--3--0--0--1--0--6--6--9--
--8--7--6--5--4--3--2-10--0--9--8--7--6--5--4--3--2--
08+14+42+45+04+09+02+00+00+27+00+00+06+00+24+18+18 = 217

3) The sum of those numbers is divided by eleven:

217 / 11 = 19 remainder 8

And the remainder is the check digit.

If you try the different possible combinations for year code and standard/deluxe interior you'll find that only three combinations in the 1980 to 1990 produce a remainder/check digit of 8. So, if I using 1983 (year code "D") for your trailer, I get this:


--1--2--7--9--1--3--1--0--?--4--0--0--1--0--6--6--9--
--8--7--6--5--4--3--2-10--0--9--8--7--6--5--4--3--2--
08+14+42+45+04+09+02+00+00+36+00+00+06+00+24+18+18 = 226; 226/11 = 20 Remainder 6

For 1984 (year code "E")

--1--2--7--9--1--3--1--0--?--5--0--0--1--0--6--6--9--
--8--7--6--5--4--3--2-10--0--9--8--7--6--5--4--3--2--
08+14+42+45+04+09+02+00+00+45+00+00+06+00+24+18+18 = 235; 235/11 = 21 Remainder 4

The point is, if you want to know what a check-digited number is and you have the check-digit and most of the other numbers in the sequence you can calculate a limited number of possible answers.

Wow....Too much info for my brain to figure, but thanks for the info. So I guess I have my answer, my Scamp is a 1982. Thanks for all the help from everyone, especially you Peter, I could have have done it without your input. This site is amazing.

Frank,
it looks to me like the VIN might have been deleted due to a crack in the tongue. I think I see another crack on the top of that member.

But, the number might have also been deliberatley changed. Just a word of warning - with no title you might be in posession of a stolen trailer. The correct thing to do is try and determine what the VIN actually is. But, if the trailer is determined to be stolen it will go back the original owner.

I am aware of 2 situations with this happening with vehicles that were stolen 20+ years ago. The new owners were unaware the vehicles were stolen.

Thanks Oliver....There are no cracks in the frame near the VIN. Three digits 1S7 were covered when someone replaced the coupler and 2 other digits were missing, per earlier in this thread.

The purpose of the thread was to find out what the complete VIN was.

I have been at motor vehicle Friday, and today, and they did not seem to care what the VIN was, and they have issued me a bonded title with the partial VIN I have now. They did not even care about all the research I have done.

MVD was not even interested in running the complete VIN as I think it is, just what they could read. It came up no record, of course, its not complete.

I know there is a possibility that this trailer could have been stolen at some point, but with no records, and a in-complete VIN, theres really no way of telling, I really just think it has been sitting around for a long time not being used.

I know I bought it, and the guy I bought it from seems to be a nice guy, so I just went with the flow of MVD.

I now have my title, registration, and plates.

It took 2 days and 4 trips to MVD, but I'm totally done, and I'm a happy camper!, I actually thought the process was pretty simple.

Congrats!!! I had a feeling it would go well with DMV, I know up here in Wa they are pretty complacent about older trailers. They just want the money. Could care less where it's coming from I guess!

Although this was a very useful thread - At least you know a little more history on your trailer, weather or not DMV cares. I applaud your research effort.

Happy Scamping!

Thanks David...I was a little nervous about it, just not knowing the past history, plus the fact that I had already spent some decent money in changing out the axle, but in the end it all went well. Now I can feel more at ease in more upgrades knowing its mine for sure.
