Hi John..!
First and foremost - WELCOME to the LugerForum!
Second, when you enter the site here:
http://www.lugerforum.com/ - on the left side, you will see a menu, just click on the "Technical Information" link, and that will help you understand how to strip and assemble your byf. You may want to do that to give it a good cleaning, inspection and lubrication...
A couple of notes here before the others help you out with their comments/advice....
If you have wood grips on your byf, keep the oil/lubricant away from them... As well, keep the oil away from the holster...
Also - after handling it - you may want to do a quick wipe-down with a gun cloth, which will remove the excess rem-oil and acid left from hands as it is handled...
Best to you - and welcome again!
