Greetings to you in TX - Welcome Aboard Here...
Is this the one you are referring to ? (Bottom Lure)
I found this old one a few years ago at a fishing flea market..
I believe the company still makes them,sinking with a rattler so the number is now 51MR and the color code 801 looks a bit darker with a orange back and belly and gold scale sides..
I haven't seen them in any local bait & tackles but you might be able to order some direct...
