Guys,
In a conversation this weekend it was raised that the MAC had a different petrol Tank on the change over from Webb forks to Oleomatic.(1948)
I have never heard this mentioned before. However there are many more out there wiser than me.
Any information?

Regards Mick.

Mick, I don't know about a petrol tank change when the Webbs were replaced with Oleos, but I have seen reference to a change with the oil and petrol tanks on the MAC with the introduction of the rear spring frame in 1953.

I have a '47 MAC (girders) and a '51 MAC (rigid w/ teles) there is no discernible difference in the gas tanks on the two bikes. I used to have a MAC with a pre-war tank that was noticeably different. The KSS/ MSS tank definitely changed when they were converted to oleo forks.

Thanks for your help on this question, it seems that different tanks on the MAC is one of those stories that get around and is unfounded.

Oooopps,

In the interest of decimating accurate knowledge I eat some humble pie. I stick with the statement that my '47 MAC has the same tank as my '51 but, apparently, that is not the whole story. Today I had occasion to pull three rigid MAC tanks off the shelf. All are post war ( I base that judgement on the type off knee grip used) but when set side to side one was different. The odd tank out is more bulbous, which is to say wider and more blunt in front. I would have to say it is specifically intended for a girder fork bike as tele fork tanks are more tapered in front to clear the fork tubes. So the question arises; was the tank changed on my '47 ? Not necessarily. A tele fork tank will work just fine on a girder fork bike but not the other way round. It is possible the last girder fork bikes came equipped with tele fork tanks. Velo had no qualms about mixing and matching when it came to specification. Their main objective seemed to be to use all the parts on the shelf. But to answer the original question, there was indeed a specifically made girder fork gas tank even post war.
