M1 Garand buttstock storage space question

[SofaGeorge]

First, thank you CMP. The quality of my rifle, ammo and your customer service are all outstanding.

Now, for the M1 Garand experts here ... I have a question about the buttstock storage space. I was under to assumption that the storage space was for a field strip cleaning kit. The ones I have seen appear to be a single tube shaped kit... But when I popped the plate I see that there are two tubes.

Does a single tube hold one cleaning kit or does something else go in the second tube? If so... What goes there?

Also, since this is my first M1 Garand I need to get a cleaning kit to go in the stock. Is there a recommendation on best kit to get. I would like to stay as close to original GI as possible.
