I think the difference between the 105 and the 102 is the color, possibly the case material also.
My 105 has an AL suffix and the case is Aluminum while the model 103 is a Turquoise/White one in a Steel case.
I noticed the set in the other thread is a different color blue, more metallic maybe and it has no handle, another variation perhaps.
Here are my two sets, the Turquoise one was a major mess when I got it, quite moisture damaged, all the paper and foil tube shields had rotted off and I had to repaint it with some off the shelf Krylon, a decent match but a few shades darker.
It was my very first eBay purchase and I paid $38 for it I think.
The Green one was purchased from a lady who contacted me through my Site as I recall, gave her $45 for it and it just needed a Damper tube to get it running, it still fires up to this day though I've never actually used it.
