Now it gets interesting
The IPL you linked to shows a L shape deck belt run used on the LRH 130 part # 532 13 12-64 which is listed as an A 78.5"
The Pix belt you showed is a 4 L which is a different section
Looks like the UK got LTH 130's with the 36" deck from the LTR .
Down here they all came with a 42" deck.
