Ryan's M3 medium

The thing was that Australia seemed to not have the machinetools to produce helical gears so they developed a straight-cut geared variation of the M3 box. Bradford Kendal I believe cast the hull and diff housings and turret. While BK took the Sentinal's castings further by employing one main casting for the hull (except the diff housing and floors as noted).

Alex seems like I need to back up here before I upset anyone.....My comments about the Sentinel were an attempt to open a debate about Ryans restoration...not so I could jibber on attempting to impress everyone with how little I know....and believe me, my knowledge in this area is very little.

I thought (wrongly it seems) the M3 bottom half was identical to the Sentinel based on what you mention above. So opening a debate about altering the M3 to a Sentinel is now a non debate.

But i would seek some clarification on the differences. The hulls to me look the same, why isnt it possible for Ryan to do a Sentinel look alike?
