Over a year ago I picked up a job lot of Coventry dies, mostly GAS, BSP, NPT formats, but some WHIT and BSF etc.
Anyway, I have finally got round to sorting them out, but in the process have a few odd ball sets. Only knowing the CH/CHS types would like information on these.
Have a set of 4 that are the same thickness as the 3/4" dies but are marked1 and 1/2" GAS, another set same thickness marked 2" NPSH. So from these two sets assume there is a die head made of a different type meant for these.
Also a set of 6 dies marked 3 BSP that are the same thickness is the normal1" die box. would be interested in knowing what type of head they would fit.
I do have copies of issue 1 and 23 of the Coventry die book, courtesy of a group member, but can not find within the pages dimensions of the dies for each size/type of head, so if anyone can provide this it would be much appreciated.
If anyone has a use for above dies let me know as I doubt I would use them.
