I have one that's very similar except the top band od knurling. Mine has a knotched center bar but no date code, 47 or 48? Mines also missint the link bar cover, does anyone know a source for them? I tried to remove the covers from a junker but of course they wouldn't come off.
It has a couple of more pictures there of the head.
This was a weird win for me...I set my snipping program a few days ago for $30...and totally forgot about it...and at work today I get a email from ebay saying I hadwon it...I thought it was a phishing scam until I actually logged into ebay and verified it.....$15 shipped....Not bad at all...what do these usually go for...sorry im a total noob..as you can tell...
