While going through some other bits and pieces today came across this JLC. Like the simplicity of the dial and that rail track. This is where I would appreciate some help. I would have assumed it was from the 40's with maybe the cal.450 but it all looks a bit to clean to my eyes. Am I away off track? If someone cares to put me right I would appreciate it and as always a rough price guide would help. Sorry was only able to snap one quick shot.
