Hate to bug ya, but ...

Not sure it is a "spin atom", but I got one that is 5.25 long, 1.07" diameter, weighs 2oz. 2 belly hooks, 1 1/8 back and 3 3/8 back. Don't know if it is weighted, but I have a small wooden atom that is very close in size and weight (5.5", 1.18 dia, and 1.9 oz) that has a 3/16 x 1 1/8 " weight pushed in alongside the through wire from the tail up to the second hook hole (which is 3.5 from the nose). Both plugs use the same size lip as the styrofoam atom jr does. I'll post a picture later. You are welcome to borrow them.

I think recall another size between the flaptail and next one down that I don't have, but have heard of people using with a skin. Probably the one you're looking for.

This little guy?

If this is it, I can lend you one. Let me know.

it's the #54 your looking for....forth one down in numb's pic. that's great for skins......the spin is like the second one up from the bottom that Danny p made and a few others, but these were not used with skins,

The 54 I have in a package is a Jr
The 58s I have is called a spin, but only weighs 7/8 oz and couldn't handle a skin (it is the second from the bottom in the picture).
Was there a 56?

Eddy, don'tlisten to these guys you'll only get confused, the one I use are a #58. 7/8'S of an ounce. Tringular file a groove just back of the lip. Small skin, 3/4 of an inch in diameter. Remove belly treble and tail hook, give the belly treble a good soaking in WD-40, couple shots over a day or two. Get a bead chain swivel ( I get mine at Red Top, they are 2-1/2 inches long and heaily built. Attach this to the plugs rear end eye with a good split ring. At the business end of the Bead Chain add another split ring and a Stainless Steel 6/0 O'Shaugnessy hook. Slide on skin and leave 2-1/2 inches of skin behind the hook at the tail end. Use a 2/0 treble attached with a split ring at belly. You won't beleive how good that thing swims and looks. Caught a lot of large fish on it back in the day both on the beach and the canal. Last hour of the west in the dead of night and let it swing, Reel only when current is not doing the job and v-e-r-y s-l-o-w-l-y. Whole rig when done is maybe 13-14 inches long.

No plug is too small for a skin, remember that and you'll do just fine.
