Dear Mr. Fox,  Thank you for your reply.  I expected that you only had
R rolls, but I thought I'd ask.  The rolls in the metal cans are also
almost certainly original R rolls.  The roll number should start with
an "R."  The RJ rolls were in regular boxes since they are smaller.

Thanks again for the response.  If you ever need help with the player,
I have experience in these and I own both an RJ and an R player.

All best,
