Piece by piece additions, sorry about them:

Unit 164 130mm Field Gun, Start date is wrong (currently 1/92). Soldiers' guide from 1980 (approved May 2nd 1979) ISBN 951-25-0135-x lists 130 K 54 (= M46) as the main heavy artillery piece. It has been used "since 60's", but I've failed to find better reference. Probably acquired at the same time as 122 H 63 (Unit 160) and could start at 1/67.

Suggestion:
Modify, start date to 1/67
