1978 BCS Mainline- what model?

[donhatch]

I purchased a BCS Mainline with the sickle bar attachment in 1978 and sold it a few years later. While cleaning out the garage I found the sickle bar sharpening attachment I had purchased from the dealer. I'd like to try and sell it on EBay. Does anyone know what models were available in 1978? It is basically a V-shaped grinding wheel that bolts onto the tractor and runs off a belt from the tractor. I'm trying to figure out what models it will fit. Any help would be appreciated.
Thanks.

I'm interested in purchasing it. I have a 735 diesel with the V-belt pulley off the front rope starter. I have no idea what it's worth as I've never seen one for sale. It'd have to be shipped to Lancaster, Wi 53813 You can call me at six oh eight seven three two five oh five three.

Thanks,

Bill
