does someone have a gauge without bevel and put some pictures here? It would be helpful to determine the right drive housing for the early sandcasts.

There are already several pictures of the early sandcast housings and I have just uploaded a post which identifies both types.

Here is a pictorial of the later die-cast gauge housing which are easily identified by the acute angle of the casting just in front (or just behind)  ;) of the thread for the cable ferule. Several pictures from different angles. KP

I posted this picture earlier  ;)
I meant, if someone post a picture without the chrome cover, we can see the complete drive housing

I don't know why I didn't think of it until now but I'll dig out my gauges for 97 and post pics of them.

Sounds great, Mark.

And there will be much more surprises, I think. It is unbelievable how many differences there are with the CB750 and there are only a few people who do care about it. But it is exactly what makes an oldtimer interesting. And expensive  :D

Here's my gauges from #97.  Doesn't look like there's too many surprises here.  At least (if I understand correctly) they appear to be the earlier, correct for this VIN ones.  Thanks for the education.

WOW Mark,

another confirmed discovery.

Also the cup/frame is different, it's nerved in the base, around the gear location.

Thank you Mark,

When I compare this one:


With this picture:


Then is Bo right that the left drive housing is a very early one.

Mark, That is a really a good bit of info. If the gearbox is as Bo has identified that makes 3 very different early drives.  When you clean these up can we get a another picture. The speedo backplate as identified by Riccardo is interesting also. This restoration project of 97 really is amazing KP

Let's not move with too much haste. We have no information on the gearbox pictured by Lecram.  Bo I would ask that you join in with this thread and give us some additional information on the gearbox as pictured as there is no history to go on or detail as to which bike this is from. Let's see some clearer photographs of Mark's instruments as we do know they are off VIN97

Yes,

we go with solid feet on earth.

Marcel, please retrieve more pics from BO, of complete gauge after and before unassembled, if possible also the vin of this (early??) bike.

Hi all.
Sounds like we have started something up. Tomorrow IŽll make pictures of  the gauges of my restored #388, #609 and hope it will bring some help. Next week IŽll recieve #849 and then IŽll check how the gauges on that one looks. If they are of the first peculiar kind IŽll make photos of them during the whole restore.
In a month IŽll recieve #421 and there might be something interesting to.
Bo

For what it's worth here are the original gauges from 576, cobwebs and all!
