This is Kodak Tri-X

Not to be confused with the much newer (and turbo-charged) T-MAX films 100, 400 and 3200 ISO

Here are some of the links to the areas I skirted over:
Silverprint - the best materials retailer (and genuine advice)
Ilford photo click on 'products'
Fuji pro - links to film info pdf + data guide
Kodak pro
Kodak B/W films
Kentmere - excellent papers
Fotospeed - excellent too + lith material specialist

Modern films are brilliant. T-Max 100 & 400 are amazing - but it gets expensive if you use T-Max developer everytime (which you should, or else there's not much point). So, age-old Tri-X in cheap D76 actually works really well if your follow this recipe...

Kodak Tri-X 400 - rated @ 200ISO
Dev 8 mins in D76 1dev+1water @ 20deg C
(Rating Tri-X at 200 ISO deliberately lets more light in, which saturates the silver halide crystals, reducing their size. Cutting the development to 8 mins - a little less than Kodak recommend - compensates for what would otherwise be overexposure)

Also:
Kodak T-Max 3200 - rated @ 1600ISO
Dev 9 mins in T-Max dev 1dev+4water @ 20deg C
(The same grain-calming technique works here too)
