TIFF image file reconstruction from Hex Code

I've been working on a "small" side project for the past year or so on and off where it requires me to extract data from a old piece of software.

It has been really fun the highs are high and the lows are so frustrating but I'm finally near the end of the puzzle I believe, but little did I know this was going to be my gray hair moment in life.

The software has diagrams stored inside 1 huge file which from my research seem to be group 4 compressed TIFF image data surrounded by some other software specific image markers.

I've been experimenting with the hex code in order to get a image output with no luck and was wondering if anyone had some insight into this sort of thing, long shot I know...

This is the header seperated from what I believe is the image data:

4D 4D 00 2A 00 00 00 08 00 09 01 00 00 30 00 00 01 02 F8 00 00 01 01 00 03 00 00 00 01 04 58 00 00 01 03 00 03 00 00 00 01 00 04 00 00 10 60 00 30 00 00 01 00 00 00 00 01 11 00 04 00 00 00 01 00 00 00 82 01 16 00 03 00 00 00 01 04 58 00 00 01 17 00 04 00 00 00 01 00 00 20 B2 01 1A 00 05 00 00 00 01 00 00 00 7A 01 1B 00 05 00 00 00 01 00 00 00 7A 00 00 00 00 00 00 00 48 00 00 00 01

The link above is what I have gotten to so far which is a 130 byte TIFF header prepended to the image data that I've extracted from the bigger 1GB data file.

Can anyone see why this would not render a image as it is or guide me in the direction of useful resources?

I've extracted what I believe to be the image data from the original 1GB file and prepended a valid TIFF header expecting a image to be rendered but with no luck, I'm not sure if I'm missing other data or not.
