Chainsaw Repair

You're right, it's an aluminum model. 

I found sources for the old A and C anvils, at least, and I also saw threads about cutting off new-style anvils to use with it.  I'm more concerned about the takeup handle, because I haven't found a source for replacements of those.

On newer Oregon spinners, they offer only 2 anvils and 2 takeup handles.  3/8 and 404 are done with the larger set, and 1/4, 3/8LP and .325 with the smaller.  Sadly I have the equivalent larger set, and the chain I acquired is all smaller stuff.

I did see an eBay listing for the same spinner, and the seller said he used the same anvil and takeup handle (the same ones I have) for every chain from 1/4" through .404.  Doesn't sound like the best idea to me...
