Reel Repair by Alan Tani

I was taking apart a 1/0 Senator i got on eBay and noticed the number 2 on spool and both side plates. I haven't seen numbers inside my other senators. Did Penn use assembly numbers or maybe the previous owner marked it for some reason?

Yeah, I've never noticed that on any of mine. So I'm not help.

You should draw a weiner on some of the internals just to get a chuckle out of a future owner many years from now.
