Using awk to output matches between two files to one file and mismatches to two others

I am trying to output the matches between $1 of file1 to $3 of file2 into a new file match.

I am also wanting to output the mismatches between those same 2 files and fields to two separate new files called missing from file1 and missing from file2. The input files are tab-delimited, but the output can be space delimited. The awk below hopefully is a good start. Thank you Smilie.

file1
Code:
1    1
2    2
3    3
4    4
     5
6    6

file2
Code:
1    1    1
2    2    2
3    3    
4    4    
5    5    5
6    6    6

desired output
match
Code:
1 2 6

missing from file1
Code:
5

missing from file2
Code:
3 4

awk tried
Code:
awk -F'\t' 'NR==FNR{a[$1]=$3;next}{if (a[$1])print a[$1],$0;else print "Not Found", $0;}' file1 file2
