28mm Gringo40 size comparison?

[Schogun]

[Sorry if this has been asked before. My search had no results.]

I'd like to do some head swaps on Gringo40's 28mm Napoleonic Imperial Guard engineers. Can anyone provide info as to size comparison with other lines, like Perry, Victrix or Front Rank? Or a head size that would best match a Gringo40 body?

Thanks

Or...the other question -- is there any evidence of Imperial Guard Engineers in the Peninsula/Spain/Portugal so I can use the Gringo40 figs as is?

Dear boy,
I think they are slightly chunkier.
The guard engineers have very large helmets .

Keep it up
