some major assumptions are being made with virtually no supporting evidence.
1. the only evidence we have that these vins are Honda font is the actual font it's self.
2. the font appears same as Honda oem font. as many 750 vins as i've seen, in the flesh and in pictures, i cannot and will not argue the font is not Honda oem. based on the font, i have to assume, at the very least, 'someone' used honda font to stamp some cases.
3. it is only natural to assume the stampings were made by someone who had access to oem stamps. the questions to be asked are: A. WHO had access to these stamps and B. WHERE did these stampings occur ? C. WHEN did these stampings occur ? D. WHY were sandcast cases stamped with 14xxx through 17xxx vin range ?
4. the cases are 9 hole sandcast cases.
No one YET has provided evidence of who stamped the font or where, when or why the stamping took place. WHY these cases were used and WHO authorized the use of these case, we don't know. (assuming use of the cases was authorized.)
"benjixt" notes his father bought a "k0" complete machine w/ sandcast cases new in 1970. "benjixt" it would be nice to see some original paperwork showing chain of ownership from Honda, to dealer, to retail owner; such as a manufacturer's statement of origin and copy of original title. (and, what is your name ?!? i wrote a couple years ago asking members who post to share their names, as a courtesy to us all so we can get to know each other better !)
i can only
ASSUME,
1. the sandcast cases were stamped at the factory.
2. the cases were stamped by a dealer or dealers after the cases left the factory.
3. a private party got oem stamps and stamped up several blank sandcast cases.
any of these 3 scenarios raises a number of questions.
the bottom line is WE DON'T DON'T KNOW. with no FIRST HAND INFORMATION or more objective evidence, only assumptions can be made.
"CBman" you ask good questions. are you saying not all "French sandcasts" have stamped sandcast cases ? How do you know this? some cases are blank ? You are saying
"many" French sandcasts ? How many ? i thought less than 10 of these "French sandcasts" exist. i do not know. does someone know how many "French sandcasts have been identified to date ? (and "CBman" what is your name
)
i'm not trying to offend anyone ! but i find not knowing who i am talking to annoying and discourteous to the group.
So: again. the cases were either: 1. fitted at the factory, 2. fitted at the dealer or 3. stamped by private hands.
Addressing 1, 2, & 3 above:
1. beginning at 14xxx, why use sandcast cases on the factory assembly line in this vin range? make no sense. doesn't seem like anything logical for honda to do. but we know other parts we've seen on sandcasts are the same yet different parts. we have no explanation. i won't theorize why, in vin range 14xxx through 17xxx, sandcast cases would have been used at the factory and not die cast cases. without hard conclusive evidence, i don't see any proof of 100% confidence a few sandcast cases were NOT fitted at the factory in the vin range of 14xxx -17xxx.
2. in the scenario of blank cases being fitted by the dealer (or dealers) after bikes left the factory, in the case of some defect or case damage a replacement case would have been used. and a dealer or dealers wold have oem vin stamps.
3. another observation; the alignment on all these "French sandcast" vins is perfect or nearly perfect. so it seems unlikely a dealer or a private party would have stamped these vins.
4. perfect alignment and oem font would be reasonable to suggest vins stamped at factory and not after cases left factory.
only someone who was present when these vins were stamped and these engines were fitted could give the answer. this is another reason any official or otherwise verified provenance could help shed some light on the "French sandcast mystery."
myself, i choose to believe the "French sandcasts" are authentic for the following reasons.
1. i believe the font is oem Honda.
2. some of the machines have undisturbed patina which "appears" to date back to original assembly from when machine was new.
3. "benjixt" says he knows the bike's provenance from when the bike was purchased new.
4. i can't imagine any motive in 1970 to put several of these machines together as a ruse or deception.
5. the only way i can be dissuaded from believing these machines are authentic is to prove at least #1 & #3 not true.
The "French sandcasts" are a mystery. we all have our opinions. good entertainment.
