Remote For Denon DRA-345R Receiver

I inherited my father's 90's vintage Denon receiver, and would like to use it for my TV sound. Unfortunately, the remote is missing. Questions:
- What is the correct remote for this unit?
- Where could I find one?
- If the correct remote is nla, I assume I can use a universal remote. What is the universal remote code?
An easy fix would be to buy a refurbished Logitech Harmony universal remote from and download the commands from the Logitech site. The least expensive remote there controls three devices and is $15, I have one and it works fine.
I'll see tomorrow morning if I can find the one I had for my 345R. I'll post back later. Bill
