I bought the 337 off ebay since I didn't have one yet in the colection. Puts me down to 5 to go to finish the collection off and the last ones will cost me a penny or two... Here's a picture of the 337 marking so everyone can see. I didn't see any real clear pics of it on here, so thought I would share this one.

Thanks Lorne. I was concerned about the font being in cursive instead of block form. But I did find the cursive dial here in the 1909 catalog A. It is not on a marginal dial. So as the years "jive" I believe this one to be correct.

grade 332 is a hunter so it has part which holds hair spring on the other side, I think you would look for open face model to get that part.
Regarding removal/installation. I have the same problem, but cant find any proper info how to do it... So far I was able to remove arm without damaging it - I used razor blade which I squeezed between arm and the bridge and gently lifted up so arm jumped off its post. I did some research and it seems to be pressed fit but I didnt tried it yet. You have to be careful not to bend pins under the arm.
