EW350 footboards ?

[EW-Ron]

I obtained these, in the hope that they will fit an EW350 project.
But the chap peddling them said they may not be right for an EW
Are they ?
The brochure pic seems to show only 2 rows of 'buttons' ?

And, are the buttons obtainable any place ?
Thanks.

Also, the alloy in these seems rather grey.
Can these be welded, or is this best avoided.

Hi the London Douglas motorcycle club  has the buttons ,there are 2 types ,flat headed and dome headed.

My 1926 EW has 3 rows of the flat headed buttons.

Most helpful.
