Compression Gauge Set

[72 C30]

New to this board. I just picked up a compression gauge set. It is I believe, complete. Included in the set are the following pieces: 1) MT-26F gauge
1) MT-26-6B adaptor
1) MT-26-10B adaptor
1) MT-26-11B adaptor
1) MT-26-12C adaptor
1) MT-26-16C adaptor
1) KRA-124A steel box
I have several questions. Anyone know what model number this set may be? Anyone know where I may get replacement washer seals? The closest match I can find to my set is Model number MT308G-B. I found that in the 1973 catalog on page 224. Although that set does not offer the MT-26-10B adaptor which is in my set. This set clearly appears to contain that additional adaptor. Thanks for any info or assistance.
