Glad, You got them..If i recall right these would be mounted on a floor stand but the flat rod maybe the wrong rod..If you were going to mount the off the bass drum table the rods would be a L-shape rods for each block..Mikey

Yeah see the weird thing is,... this is the second time I saw those same mounting brackets attached to a flat rod like that. The flat rod on my set looks like there are two points at which there is the same wear pattern,..as if something slid onto the flat rod or something to attach them to yet another piece of mounting hardware?? maybe??

Otherwise, those individual mounts to the temple blocks have no area for the round vertical rods often seen that mount off the trap tables. Heck there's not even enough room to drill a hole in the top of the back of those mounts and mount them to the rods off of a trap table! (I had briefly thought about doing so,.. but did not want to ruin the mounts!)

Let me check my old catalogs later today.But,I also have seem the blocks mounted off the edge of a table on the bass drum with C-champs at each end..Mikey

I've seen the rails that you have mentioned to me where there are small arms with C-clamp type of mounts from the rail to the drum hoop,... this is definitely NOT that same setup. This little rail is just a flat piece of metal, about 1/2" wide and 1/8" thick. No holes in it, nothing.
