Hello

I can't seem to find that model could you verify? Here is a link to a GCS29 will this work?

I will keep looking but let me know if this helps.

I am going to list this as an answer but only click accept if it helps.

Thank you

Hello

OK some of the old information is very hard to find. Did you find what you need? I can pass this along to another expert and see if someone has any information on equipment that old.

Thank you
