I built an Emperor Model 120 with a Model 100M movement back in 1976. I don't know if my assembly instructions are the same as your Model 150 but I can make you a copy if it will help. This is my first visit to this site so I don't know how to get the info to you. Any ideas?
HI Dennis, You could leave an email address or put the instructions on Dropbox.com and post the link here.
