Thanks for the various replies. Here are answers to some of the questions/suggestions switching the winding shafts doesn’t work because the no7 I need is significantly larger than the bore of the no6. i do have a set of chinese winders too, but as noted they’re movement specific and none fit the bill here. I don’t want to replace the mainspring a)because I like to keep things as original as possible and b)where I live it’s tough to import parts so i have to wait long periods between supplies so in conclusion I expect to be handwinding the spring this weekend -
From the photo the pallet arm looks as if it has been tampered with the edges are not nice and straight this can cause problems on the banking pins. -
Update, I discovered that I could change the mainspring by removing the arbor and sliding it out from between the front and back plates. So I put a new mainspring in. This it what I get over a 7 day period After winding amplitude is 1 1/2 turns plus a few degrees. ie just over 1 1/2 turns. 1 day after winding gained 1 sec no amplitude check. 2 days after winding gained 1 sec amplitude 1 1/2 turns i.e. it lost the few extra degrees 3 days afer winding gained 3 sec no amplitude check 4 days after winding gained 5 sec amplitude 1 1/2 turns i.e. unchanged 5 days after winding gained 7 sec no amplitude check 6 days after winding gained 16sec amplitude just over 1 1/4 turns 7 days after winding gained 24sec amplitude 1 1/4 turns. From Based on video inspection, I am getting full pallet lock. So, my data seems to be at odds with the statement "swing of a balance wheel has nothing to do with the rate". However, I have noticed the banking posts are not controlling the lever position on the right side. I may have some work to do here. -

I can't tell whether or not some stem is stuck in the crown, I think so though. If the crown is stainless steel you could try alum to disolve the stem of try drilling it out. If all else fails, buy a new crown. -

Does anyone use the x5 eyepieces, when i use them on my different amscope , the magnification changes to x5 but the field of view remains exactly the same as the x10, so nothing gained. The optical lenses can't be swapped out or at least they are not available as far as i know.
