do any photo etch sets exist for the tamiya 6-pdr at gun, or the italeri one?

im building a dio involving one of these little brutes for RMG, but because its an old kit many of the parts or very thick or overscale, especially the gunshield.

ive tried the usual suspects, aber,eduard etc but came up with nothing

does anyone know of a set, or do i need to get the plasticard and rivets out?

cheers
