Enfield front sight blades interchangability

[Power Pill]

Are the front sight blades interchangeable between No1 and No4s?
Im looking for some front sight blades for my No1Mk3, but all i've found so far are listed for the No4.

Thanks!

No they are not,and there are 2 different types of blade for the No.4. Marstar and Tradex both show No1 blades in stock,give them a try.

I thought the bases were the same. I'll have to look at my #1s
