I also use Newton Ellis and find them to be excellent. Over the past couple of years they have brought back to life a Rollieflex 3.5F which had been bounced (not by me,btw), a 150mm. Hass. Sonnar, a Hass. ELM body, a Zuiko 50mm. f1.4 and a Swift Audobon 8.5 x 44 bino.. Old gear yes, but now as good as new. They have been in business for many years on Merseyside and I can thoroughly recommend them.
