Vanquisher cannon, made by a Lemar Russ'one and a pen. It can get up and down.
The latest comparison. Chimera turret would be inserted in the Leman's one, maybe like M60 Patton tank.
Conclusion. I'm ashamed to leave this work incomplete, anyway it's clear that a Chimera can be converted to a Leman Russ. A reversible trasformation.
It's sure that a new Leman costs less too.
