Hi guys!

I am sorry if this thing was mentioned somewhere on this forum, but could someone tell me what track type did M3A1 had?
So far I was able to dig up only some dimensions, like here:

The thing is I have the 1/72 Hasegawa M3A1, but as some of you braille scale guys are aware of Hasegawa's vinyl track "quality", I would like to try and find a replacement.

Also, if any of you know of some resin or PE track that would fit to this kit, I would be very gratefull for shared information.

Thanks!
