Identify this IH fertilizer attachment on a toolbar?

[Super A]

I brought home a toolbar with four 185 planters on it. It is also set up to apply dry fertilizer in a band beside the row. Unfortunately the fertilizer hoppers were gone, but the bases indicate it's the same style hopper used on the Cub or Super A or similar tractors. Can anyone tell me what model fertilizer attachment is on this unit? I have looked on the caseIH website but can't find anything that looks like it. Basically it's driven by a tire/gauge wheel, one wheel drives two rows. The openers are single disk, never seen anything like them in IH either. Any ideas?

Thanks,
Al

IH used that setup on many planters I bought one with 184 planters on it set up the same way

[Super A]

I figured it was a standard/common unit for IH. Any idea of a model #? There weren't a lot of IH planters ever sold around here and I have never seen one anything like it before. My dad had a set of cole planters on an IH three point hitch cultivator with something similar but I think it used a big rolling coulter/wheel to run the fertilizer attachment.

I first assumed that the hopper brackets were exactly like the Cub/Super A. I haven't looked at them side by side but I believe the bearings, and the way the brackets are cast to hold the bearings on which the hex shaft turn are made different than on a Cub/Super A attachment.

I will probably end up offering the fert. attachment for sale and would like to know what I'm selling first!
