Here’s my experience.
I’ve just bought a second-hand Morso from a chap via the forum who’d himself purchased a replacement measuring arm for the machine from Framer’s Corner before putting it up for sale. I bought the Morso knowing that he hadn’t actually fitted the replacement arm yet and so it was only when I received the machine today and tried to attach the arm that I found it wouldn’t fit onto the machine because the screw holes don’t line up with the Morso.
I asked the chap who sold me the Morso to ring Framer’s Corner about the problem and he said they told him that apparently the measuring arm they supply only fits SOME Morsos but not all (depending on when they were made, it seems). They further advised that they were unwilling to accept the measuring arm back as a returned item and that it was down to the owner to drill out additional holes in the measuring arm so that it fits the Morso.
Now, according to my guy, when he had originally enquired about purchasing a replacement arm from Framers Corner, they DIDN’T tell him that it only fits properly onto some Morsos. I myself had also spoken to Framer’s Corner before agreeing to purchase the Morso to make sure their arm would go onto the machine I was buying and was also told absolutely, yes, the arm can be used on the Morso because they’d copied the Morso exactly in order to produce their own guillotine machine.
Personally, I feel aggrieved by all this, and I know the chap that sold me the machine with the replacement arm feels bad about it too. Framer's Corner should have explained that the part might not fit the Morso before selling it to my vendor, and for them now to expect either him or me to deal with it I think is right out of order. As a new framer in particular, it's really disappointing that they've taken this attitude. If I were in their shoes, I'd be going out of my way to salvage the situation, but based on the conversations had with them today about this, they don't really seem interested. Of course drilling some holes isn't the end of the world, but it's really p*ssed me off all the same.
Anyway, my personal dissatisfaction aside, just be aware of this if you’re in need of a replacement measuring arm!
