Hi, I'm new here. Recently dug my Dad's old Canon F-1 out of storage and I would like to use it. So basically wondering where I can go to get the adaptor for the battery. I believe mine is one of the two earlier manual models with just the meter being battery-operated. The camera itself appears to be working, so I just need to find a place that can put in the adaptor for me, and maybe give it a cleaning. I did see the thread on camera shops, but can't seem to find anything on places that service, so I'll appreciate some pointers.

Thanks to all in advance, and apologies if this is one of those asked to death noob questions.
