Headstock castings

Are the headstock castings interchangeable between models?
I have one that is broken where the speed changer attaches the previous owner used big washers and epoxy
to put it together .... didn't work well.... it's a 1956 Greenie MK V 500, will any MK V casting work?
Will everything line up and fit?

I have not done this so I do not speak from experience but I believe that answer is an emphatic YES.

This is one of the unique characteristics of this wonderful toy we have all chosen to play with. Parts interchangeability and availability has been maintained over these many years. I know some people who prefer the older castings.

The PowerPro, however, has sorta put an end to this.

So if I choose to upgrade to a power pro DIY version in the future is one casting preferable to another?

The key word here is preferable. The answer therefore is Yes. Which one is based on the preference of the person asking.

There is no right answer!

My preference is an "A" casting. I have one already 'waiting'.

It is rougher(sand casting rather than die cast), but is heavier(thicker).

Obviously if a power pro upgrade works with all casting versions, a 'standard' set of innards will also.

I have a brownie/goldie casting that you're welcome to for the shipping.
They don't weigh much. I would rather give it away than see it get melted down for scrap!
Where do ya live ie, zipcode?

I recommend the "C" housing casting due to the larger access hole under the Logo cover. This casting is stronger in the area where the speed contrl assembly attaches. I also like the removable switch tab on this headstock.

However all the "A","B" & "C" headstock casings are interchangable with very minor changes.

How can you tell "A" "B" and "C" apart?

C castings have the plastic safety (red) style rocker switch. The logo plate on the back is big and attached via screws such that the bottom screw allows the logo plate to swing out of place.

B castings are what you will find most often. Toggle style metal switch, logo plate is attached via the spring clip.
