As Ron said:
The 110pF caps inside the backelite blocks ARE NOT mica caps, but ARE PAPER caps.
While they are not used in any place that could cause safety issue, they will be leaky as any paper cap, which could be easily determined by disconnecting them prior to gutting, and measuring with good meter (a DMM will not do, they typically are limited to 100pF, though you could use a Delta mode to compensate for the probes). So, the performance of the radio will be affected in an unknown way. Perhaps even unnoticeable.
But my personal rule is same as Ron's: if it paper, it has to go.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
