Dale,

I'd have to see a close up of your logo to be sure, but it (and Bernie's) just looks like a "light stamp" and not an etch. Maybe DW can tell us when the shop got in the pneumatic? stamp (Thanks, DW). I believe your knife is pre '72. Otherwise the two thick reds would be brighter if it was '72 or '73.

Griff,

I know what Dave sold the 4-7 for, but the knife changed hands twice since so it wouldn't be cricket to disclose that now. Suffice to say it was pretty much nosebleed territory for a non fighter because because of it's rarety.

Best,
