Uli - i believe your vin is currently all apart, correct ? 

If so, then now would be a perfect time to make a list of every part you find stamped with numbers, letters or characters.  And photograph these stamps on each part.

You would be doing a huge service to SOOC !

"four  Honda" .....That was a joke.

But.
If my diecast and my sandcast and yours have 4H on the showa shocks, what would that tell?

[Steve Swan]

Uli - the reason i ask you to make a list of stampings found on all the parts of your vin:  then we canb use your vin as the basis of comparison to all other stampings we find on our vins.

to know what we talk about what we think, consistency must be established.  if we have the stampings on each part on your bike, then we can compare and contrast stampings we find on parts of other parts from other vins.

if we do not begin identifying every stamped number, letter and character found on parts we have nothing to contrast or compare so we can establish a pattern of consistency.  

Uli - i am sure you understand the importance of this and why we need you to find and photograph every stamping on all of your parts.   You can make a very important contribution.

"IF"....  ifs and buts were candies and nuts, wishes would be fishes and pigs would fly.

"IF" = "We don't know."

i'll photo what i can off of 2157 and 232. 

232's disc is stamped "Q 42 B"  i have no reason to doubt the disc is original to 232 coming off the assembly line, the 232 chassis was very complete and unmolested when i took ownership.

Thanks Uli, if you have more, please keep the pics coming.

rear shock: 4H  plus character

[4pots1969]

Uli, thank you very much for the pictures...

I can't remember who makes the Z1 shock I'll try and do some research
I like the 4 H (Honda 4) reference Seems that H is not a month code then
Have a look at my attached photos of some K0 shockies They have the 4 and what I initially thought was an "S" but could also be a "J"
Also note the 2 very different symbols on each shock Now these are pairs so the different symbols are different on each single pair Why is the $million ?

Uli, Those are great photos contributions to this thread. One can presume that your bike has a collection of May 1969 dated parts. Anyone else have good records like these.

This is the item that has always had me intrigued. The Q and the B is of particular interest The 42 could be February 1969 maybe

Uli, super contributions.  now we have stamped characters to compare to what else is posted to establishes differences and consistency.  THANK YOU !

[Steve Swan]

we really need someone who can interpret Japanese characters !
