Ok, after the success I had in confirming the thread size on a Faber tank I have (another post) I am now trying to do the same with an IWKA steel tank. IWKA are out of business apparently so no help there 
Tanks is a UK tank marked:
IWKA 0-761 EB581
BS5045/1/CM/S
TUV 1.5
TARE WT 13.14KG WC 10.0L PZ
WP 228 BAR TP 397 BAR
I *think* the valve is 3/4 BSP - but am hoping someone can confirm? Tank is definitely pre-1994 - but I cant find a manufacturing date anywhere. Its all in test and good (I've been getting it tested without issues for 20 years) but has a yoke valve and I've moved to DIN. Its a pain using adaptors. Want to buy a DIN valve but need to be sure I am getting the right one. Neck is NOT marked M25 (which I understand it should be if it uses that thread?) and I'm assuming that as a UK tank it would not be 3/4 NSP. (US thread)
Thanks
Al

update - still cant find the manufacture date but found an early test of 4-85, so its at least that old.
