That is great, that there is some interest.
Hopefully somebody will be putting them to use, rather than just trying to re-sell them.
Are they going to IARC members? That would be good to see some new people using test gear. Even if is old gear, it is still useful.
The LG scope and the SG-8 sig gen are still quite adequate for most things. The Heathkit VTVM is a desirable classic, and was found on the vast majority of test benches back in the 1960's and 1970's. It still very useful and desireable. It's primary attribute, and main claims to fame ( good accuracy, low price, and high input impedance) is often no longer needed with the advent of inexpensive good quality DVM's.
