It says ReadyNAS DUO,

So you have the original Duo (using a sparc processor, and running 4.1.x firmware).

sticker on the back says Readynas DUO RND 2120 V2

Netgear should have done a better job with branding, but that ship sailed back in 2011.

The sticker means you have hardware revision 2 of the original Duo (not the Duo v2 which uses an ARM processor and runs 5.3.x firmware).

Can someone please help with an idiots guide to fixing the TLS 1 issue

As Sandshark​ says, the TLS issue blocks web admin access (Frontview), not file transfer.

One workaround is to use FireFox as the browser and set security.tls.version.min to 1 (browse to about:config and search for the setting).

Once you have access, you can also modify a script on the NAS which will let you access Frontview using unencrypted HTTP in any browser. There is a step-by-step here:

ability to transfer files to the NAS?

This requires the SMB 1 client to be enabled.  On windows, go into "turn windows features on or off" to enable it.

There is no way to enable this on a Mac, so you'd need to enable AFP as a sharing protocol.  Though Apple is planning to remove AFP, so this will be a problem going forward.  You could also try NFS.  

Another path is to use FTP - there are several clients that work, including WinSCP (Windows only) and FileZilla (Windows and Mac).  Not fully integrated into the OS, but transfers are possible.

You are using a very old NAS (discontinued 14 years ago), so at some point you will need to switch to something current.
