Need advice

Hi. I have been asked by an elderly lady whose late husband had an Asahi Pentax camera and various lenses, to get them valued. As I know nothing about cameras I was hoping to get some advice from anyone on here. I have attached a few photos of the camera and lenses with their own cases which seem to have come from Wallace Heaton Ltd London. Any information, value, or history about them would be greatly appreciated. Her late husband passed away a number of years ago but I do know that he was well travelled and I would love to have met him to hear the stories of his travels over the years. Thanks for reading.

Probably your best bet would be to go to https://www.mpb.com/en-uk/brands/pentax/ and get a quote from them
